At MP1, all creatures in all acts are level 63 on inferno. The only scalar difference in terms of monster difficulty between acts is if there is no MP enabled.
Just as a good metric for weapons, a mace with 905 dps (500-1009 damage range, 1.2 speed) with the same exact stats as your current mainhand gives you almost 7k more dps (with shout up). If you got that dps and got around 100 strength instead of the int on it, you would gain around 10k dps. A decently high dps mace with str, LOH, and a socket(or >70%crit damage instead of the socket) should be pretty cheap. If you get a mace like I described, you can afford for it to either have much less LOH, or none at all as you are nearing the threshold where LS > LOH.
If you were wanting to farm higher MPs, your top two concerns are going to be getting your crit up, and getting your AR up. One of the two best sources of crit is the neck, and you have no crit on your neck. You can find one with somewhat similar stats, only with crit for a decent amount. For you personally, every 1% crit you gain is equivalent to 26 strength, so it would not be a big deal at all to lose a bit of strength. Your rings also both lack crit chance, you can afford to drop the vit for the crit chance on both, as you don't need that much health at your current gear level. Once you get your crit up to around 45-50% after shout, you want to get strength, IAS, and crit damage wherever you can, but strength should be a priority until you get around 2100 or so.
In terms of gaining AR, you can find a good set of gloves with similar stats to yours, but with much higher AR for pretty cheap. Gloves only tend to get outrageous when you are looking for trifectas. Your belt has no AR, and can be pretty easily replaced by a much better one for cheap. Depending on your budget, I would consider getting a Lamentation with high str, good AR, and whatever else you can get stat wise... it will probably have low or no vit, but thats okay, or you may consider getting a well rolled IK belt (though much more expensive). Speaking of IK items, you would really see a massive boost in survivability if you got the 2 piece bonus, most easily acquired by getting belt/glove or belt/boots.
Realistically, if you are looking into getting into MP levels past mp2-3, you would want to gain between 100 and 150 more AR, and get your crit up by 5-6%. These two goals will have you comfortably farming mp3 (though neither fast nor efficiently). Even with the improvements that I mentioned, it is still best to either farm on MP0 or MP1 at your gear level both in terms of efficiency, and ease.
Thank you for that :).. luckily I just found rare pants with almost exactly these stats, vit is 186, but they have some extra armor.
But I´m interested in those 2x1h builds, but I´m not really sure how to select weapons. But I just found amulet which increase my budget by maybe 200-400mills.
2x1h builds for HOTA depend on crit damage/chance and attack speed, axe MH (high dps EF is better than an axe, but really expensive), sword OH is usually the norm. Highest attack speed and damage you can get. This build tends to be really expensive to set up, but once it is fully set up, the speed is insane. I am going to get really in depth here, but my intention is not to say your gear is bad whatsoever, but rather give you advice on how I would personally upgrade from your position. Your armory is a little bugged or something for me because you have no gem in your helm or weapon, and are missing the left ring. Assuming you have a good ring along with a 80% or higher gem in the weapon, you should be able to handle MP5-6 Ubers with a group, and MP0 should be a breeze (btw, if you want to keep your current gear, I'd look into a rend build). You can also use my suggestions to further improve your WW spec, but replace the sword offhand with a dagger (for WW barbs, the dps of the offhand doesnt matter as much as the stats. try for the same stats as the sword, but with higher stats, and as much strength as you can get).
Overall, you can make several optomization changes that will give you a much better experience as HOTA spec. Swapping your helm for a great Andy Visage, or if you can find a mempo with crit for cheap will be one of the biggest straight DPS increases. You do also have the option to go for a higher strength IK helm, but it wouldn't be nearly as beneficial. Swapping the IK belt for a Witching Hour could net you anywhere from 20-40k dps easily. Grab yourself a good EF or a high dps axe with crit damage, and attack speed for the mainhand (with a socket if affordable). For the offhand, its basically the same deal for stats except a sword is preferred as well as possibly getting some lifesteal. Replacing the boots with great Fire Walkers or Ice Climbers would also be pretty great for you as they have tons of stats (the bonus vit is nice), and allow you to get pieces with lower defensive stats in other slots. You want both your rings to have strength, attack speed, crit chance, and plus damage if possible within budget, but trifecta's are always expensive. You are in a tough spot with those lacuni bracers, as you would ideally want a set with crit, but in order to get one, you would likely have to sacrifice most/all of the strength on them. If you end up swapping your helm and belt out, you can get a fairly well rolled set of IK gloves for a decent price, but they will most likely be missing the vitality having much more strength along with AR to boost survivability (replacing the boots with high str/vit ones also immensely helps this). Grabbing a set of Inna's pants would also help your attack speed and crit chance, but you will lose str/vit for doing so, and it is an incremental upgrade best kept for last.
Now, I am NOT saying your gear is bad by any means whatsoever. I am just telling you items you want to shoot for as you snag upgrades for HOTA spec. Assuming your amulet sells for the middle ground of 300 mil, you would want to allocate a large portion of the profit to weapons and jewlery. Amulets and rings are one of the highest dps items you can get in the game and since you dont have very defensive jewlery, you could just go for trifectas without any defensive stats. If you want to stay HOTA, and are wanting to go 1h HOTA, then you would want a lot more IAS, so after getting weapons and jewlery, it would be best to get a Mempo/Andy's helm next as those are good sources of more attack speed, have higher end strength, and have good crit (if you're willing to pay for it lol). Dropping the 3 piece IK bonus wouldn't result in a huge survivability decrease as long as you keep the 2 set bonus (you can even grab those IK gloves for the damage decrease they offer). Chest/Gloves is the best 2 set for IK due to how much better your choices are for the helm, belt, and boot slots are. If you want to run the 3 set bonus, I would go with IK boots so you can still keep the Witching Hour and Andys/Mempo.
I also urge all Barbs with over 450 AR to drop impunity for Overpower- Crushing advance due to the extra damage along with the huge survivability. With enough crit chance and attack speed, you can keep it up 100% of the time. As 2x1H hota, you can swap unforgiven for bloodthirst passive for a good amount of LOH, as well as the ability to make up for the loss if you get a witching hour. You can also swap the bash rune for any other bash rune due to the high attack speed of this spec giving you tons of rage really fast.
I went ahead and plugged your gear into d3 rawr (http://www.d3rawr.com/d-2e4Ei), then tweaked the sets to show what the upgrades would net you. Set 1 is your gear as it is on armory, but I went ahead and put an 80% CD gem in the weapon, a red gem in the helm, and threw in a basic mid tier ring in the left ring slot since it was missing on armory. Set 2 shows what would happen if you upgraded to the lower end of what I suggested: andy's helm, fire walkers, a simple trifecta ring for left slot, right ring changed to a slightly better one for you, 1h weapons (very good EF and a sword), a neck with better str/vit (which should be really cheap to find similar on the AH), mid tier IK gloves, lower end mempo, and the legs you mentioned in your post. Set 3 is the same gear as set 1, but with the same 1h weapons from set 2, and decent fire walkers (that should cost under 10 mil). The dps numbers include Battle Rage, and I swapped impunity for Overpower-crushing advance (this applies to all 3 sets) to show EHP changes. I also gave you bloodthirst to show how powerful it is as a healing ability. Adding Inna's temperance pants would add around 8k more dps to set 2, but would lose you a lot of str and vit. The second set could be much better, but you get a rough idea of how much the changes effect your character.
Though the dps difference between set 1 and 3 is only 4k, and that you lose like 3k hp, the difference between your life gained per second (while hitting enemies) is 3k more for set 3. The DPS gain (on paper) is also pretty far off from what it would actually be due to the inability for the site to factor into the fray into the frequency in which you can use HOTA. The best metric that I can use to measure the actual dps difference is the tDPS tab on the right which calculates the dps of the sprint tornadoes + whrilwind damage. Set 1 is 430k, set 2 is 610k, and set 3 is 493k. WW dps is very different from HOTA dps, but it should give you a good idea of what the diffrence is between 2h and 1h weapon specs. The difference in attack speed is extremely important for both HOTA and WW barbs, and generally outweighs the higher top end damage output of 2h weapons. With your almost 50% crit, Overpower-Crushing advance should almost always be active on you, even without higher amounts of attack speed. Seeing as you have 8 seconds between when the 30% reduction falls off, and the end of the cooldown, chances are that you will land enough crits in that time to reduce the cooldown enough to have it up 90% of the time on the lower end.
Sorry for the huge post, but I really havent dived deep into someone's profile in a long time, and I dont mean to steal this away from the TC either.
Bottom line on finding an upgrade versus buying one: Probably wont happen. The way the market is right now, getting upgrades at lower gear levels is really cheap. It is more worth it for you to farm alkizer runs (or whatever run you prefer) for gear/gold to use to buy an upgrade than it is to actually try to find an upgrade as a drop (at least for times sake). For your time (and barring the gods of RNG), it is better spent doing runs to get gold/that occasional good item drop for upgrades rather than just trying to find one. As an example, the last time I actually found an upgrade for my barb was 2 weeks ago... the last one before that was before MP dropped (hell probably before even 1.2 dropped). After the initial gearing period, you will be very lucky to find an item that is a really nice upgrade, even with the improved drop rate.
To further expand on LS versus LOH, its actually best to get both stats if you can afford it. Without a link to your profile, I cant say what pieces are in more dire need of an upgrade over the other. For example, I run 8.8% LS and like 300 LOH right now (110k dps), but back when I was at 63k dps, I ran about 1200 LOH and 4.6% LS. There is also playstyle to take in to consideration on whether or not LOH is better than LS below 65-75k (which is usually the breakpoint where 900 LOH < 5%+LS). If you tend to use your actual whirlwind along with your tornadoes for damage, than LS is pretty good for you. There is no definitive DPS number where LOH becomes magically better or worse. The determination is mainly made by factoring in crit chance, crit damage, attack speed, and strength. You can use d3rawr to enter your barb's gear and using the tDPS tab on the right, see how much LOH = 1% lifesteal for your gear). The "magic number" that you want to hit is basically the point where the value of LOH is less than LS to the degree where making up the difference is a detriment. To put it more simply, once getting 2.5% is more worth getting that slight upgrade to LOH, then you hit that level. If you dont want to use any sort of online stat calculator, the only real way to find this out is trial and error. Like i said before, roughly speaking, at around 65k dps, the value of lifesteal begins to overtake LOH in terms of overall healing. Remember that LS procs on ALL DAMAGE rather than having a proc coeffecient like the sprint tornadoes do for LOH. 65k dps is also the point at which many of my barb friends begin getting more aggressive with WW, and use it more to damage rather than as a way to clip through enemies. WW only benefits from LOH for the first tick of damage, while LS is generated from every point of damage done.
Now this part is very important:
part of upgrading is to understand each items and how they come in together in the end not just individually, say u have very high str shoulder but no vit what do u do? well u can try get vit on every other piece or get massive one on chest or pants.
What this should say to you is to try to build a set on balance rather than getting all perfect items right now. I was exactly at the spot you are at a little while ago, and what I did was build my set based on rounding out my gear, so to speak. Depending on your budget, you may want to get those gloves that have str, AR, crit chance and CD, but have no vit. You may want to get that neck that loses you 3k HP, but gives you 150 str. You can make up for the losses with other pieces of gear. The tryhard budget barb video actually illustrates how you can put together a set of gear by having pieces missing one or two stats that would make it otherwise godly.
As for upgrading big versus small, its mostly on a case by case basis. It really depends on what slot you are looking to upgrade, and the item in the slot itself. If its a neck with like 170 str, 100 vit, AR, and +armor or something, then it would be very worth it to spend a lot of gold for one with crit chance and crit damage (or attack speed). What I can say about lower gear levels is that since your strength isnt very high right now, it should be your main concern as long as you can keep most of your other stats. Right now losing crit damage wouldn't be quite as damaging if you could gain a decent amount of strength. More to the point: at your gear level, going big on upgrading the worst items will give you the most overall benefit right now. I know that seems sort of common sense to say, but rather than upgrading X,Y,Z slots with medium upgrades, you would see a very noticeable difference if you picked up an upgrade for the worst item at a higher cost. At MP0/1, you can afford to drop some HP/AR for dps, and probably should consider doing so as dropping (or lowering) those defensive stats makes for a much cheaper and bigger dps upgrade.
Now as you are farming MP0/1, you can lose quite a bit of HP in favor of DPS as monsters wont hit you very hard with that level of AR/HP. Dropping vit in favor of very high strength/AR/crit/critD/AS will net you an overall huge upgrade. Bloodvaga is spot on when he talked about moving into the 100k dps range too defensively. You can likely drop down to 35k hp and see not a huge difference in survivability if you keep that LS/LOH as high as it is right now. Dropping 7k hp would likely allow you to get your DPS up by a whole lot, more than 20k pretty easily depending on how much vit is on the item that you are replacing. As far as 1h vs 2h goes, a 2h WW barb requires a TON of gear to be efficient, and frankly isnt worth building to unless you have a serious bankroll. Now I am a somewhat strange breed in that I am only just now beginning to worry about getting attack speed rather than trying to get it all along. Now i am going to get mathy here, but unless you can get to an attack speed breakpoint (the point where your WW/tornadoes will tick 1 extra time), I would somewhat urge you to put it lower on your priority list. For this reason alone, I use enchantress rather than scoundrel as my follower due to the fact that her attack speed buff puts me beyond that breakpoint.
Specific legendaries that are cheap for good stats (at your gear level):
Lamentation belt: Seriously a great belt if you can afford to either drop vit or AR. On US servers, you can get one with 180+ str, 80 vit, 2.7% lifesteal for under 1 mil, and they even come with 1% crit along with a bonus to an ability.
Unity: high strength, 4.5% or more crit, + damage affix, and LOH for really cheap if it doesnt have crit damage, vit, or AR
Strongarm bracers: only if you must, as many rares are better, but these usually roll really nice and are dirt cheap again. High strength roll, % life, 3%+ crit.
Fire Walkers: EASILY one of the most underrated items in the game. Capitalize on this as they can have ridiculous stats (though not ice climbers). I got my 160 str, 140 vit fire walkers for 500k. They automatically come with fire resist and 12% runspeed, which is very nice, and the extra 4-6k ticks from the fire trail adds up quickly.
As for specific to slots, at your gear level here is what I valued when I had similar gear to yours(spoiler tagged to save space):
Helm: 50+ Str, some vit, 45+ AR, 3%+ crit chance, socket (ones without sockets are dirt cheap though and have better stats) Neck: High (130+) str, 50+ vit, 8%+ crit chance, LOH (crit damage or +dmg if you can afford to drop LOH) Shoulder: 150+ str, 80+ vit, 55+ AR, and either life% +armor or phys/fire resist Chest: 80+ str, 60+ vit, 2-3 sockets, 55+ AR (these days you can find ones much better than the stats I listed with only 2 sockets for really cheap) Legs: Basically the same as chest except 1 socket and higher vit than str (2 sockets are really expensive) Belt: 180+ str, 60+ AR, 2.5%+ LS, and basically any other stat that isnt +health to globes
Gloves: 80+ str, any vit (or none depending on if you want crit damage/AS), 40+AR, 9% crit (8% if going for crit damage) Bracers: highest strength i could get, 40+ AR, 5-6% crit (adding vit multiplies the cost at least 10fold) Rings: +damage (a seriously underrated stat), 100+ str, 3%+ crit, crit damage/AS if i could, if I couldnt get crit damage/AS, vit/AR, and MAYBE LOH depending on the cost. Feet: (this was before the price for firewalkers plummeted) 120+str, 100+ vit, 10%+ movement speed, and AR if it was in budget.
Weapons are a whole other beast. MH Weapon: At your gear level, the best choice would be to go for the highest dps mace/axe you can that rolls crit damage and MAYBE str/AS. I know that it feels wrong to possibly lose a socket, but if you can go from an 830 dps 100 str 40% crit damage socket weapon (with a 60% gem) to a 1k+ dps weapon with any str, 60%+ crit damage, and possibly AS, you will see a HUGE difference in the damage of your tornadoes and the whirlwinds themselves. I personally am a fan of maces as they have the better damage range (the 515-1064 damage part below the dps number). Depending on your gear (again since your str is low, I would probably prioritize getting that up above getting new weapons), your most expensive upgrade will be here. If you can get your strength up, splurging here is a really good idea as the sprint tornado ticks are based on your mainhand damage only. OH Weapon: Stats. Nothing else really matters until you begin using WW a lot more. You want a sword or a dagger offhand, but daggers are the way to go unless the sword has enough attack speed to put it above 1.5 weapon speed. For individual stats, get the highest str, crit damage, lifesteal dagger you can with a socket. You can swap LS for high LOH if you want, but once you get above a certain threshold (determined by gear), LS is better.
TLDR: The easiest way to know how much a given increase of each stat would benefit your DPS, use something like d3rawr.com or d3up.com. Those websites both give you specific amounts that increasing any offensive stat would increase your dps. d3up.com is great for determining what item is giving you the least benefit in terms of EHP and DPS which is very nice, while d3rawr.com gives you in depth data for dps (such as what your ACTUAL dps is with tornadoes, and also how much LOH is worth 1% LS). At lower MP levels, you can sacrifice a lot of vit/AR for dps as enemies dont hit very hard, and should die too fast to damage you too badly. It is more worth it overall to upgrade your worst items first, even if there is a bigger upgrade for a better item because those upgrades will be cheaper, and have more of an impact.
You dont honestly need 24% movement speed, but if you really did, than you would just need to replace the spear with a dagger, and get her some fire walkers (or any other boots with 12% runspeed). I run with 12% runspeed, and clear really fast as it is. I tried out using a similar lacuni bracer to hers when one dropped, and I really didnt notice that much of a difference versus 12%. I moved a bit faster, and maybe hit an extra mob a little quicker, but i really saw no discernable benefit.
If you swapped her mainhand spear with a mace with the same str, IAS, dps, socket, but with no LOH, and 50% crit damage, she would gain 6100 dps. If you swapped her offhand spear with a 738 dps dagger with 115 str, 2.6% lifesteal, 500 LOH, and a socket (with a 70% gem in it), she would gain 5400 dps. Even though she would lose a net 180 LOH and .3% lifesteal between the two new weapons, she would end up gaining 400 more life per second (not including the life regen from the shoulders) because of the difference in her damage overall. The dps gain is in large part due to the 10% bonus crit that she would get from swapping to weapons master and having a mace in her mainhand. With above 45% crit (after battle rage), WW barbs do not need animosity due to how fast they gain rage (especially with her having 55% crit now that she would have weapons master).
If she were to swap the shoulders for ones with similar(or more) str, no +armor, no regen, maybe slightly less AR, but with at least 26 vit, she would net gain survivability (26 vit is equivalent to the +265 armor in terms of survivability). For another big upgrade, you can grab her an IK helm that has on the lower end of strength (under 100 ), 5% crit, 10%+ life %, and a socket for extremely cheap. You can also just find a similar helm (that just isnt IK for probably under 1 million and may even have AR or vit). The nice thing about getting the IK helm is that you not only get the 2 set bonus (netting you 60 AR for free), but the helm also offers 5% less damage taken from melee.
I uploaded her character to d3rawr and swapped in the gear that I suggested with around the stats that I said. Set 1 is her normal gear, with nothing changed at all. Set 2 is with a new helm, shoulders, bracers, and the two weapons. With those 5 items, she would gain 20k damage which is actually gaining 90k true dps. True DPS is the actual DPS that she will be doing with her sprint tornados + the whirlwind damage. She goes from 158k tDPS to 249k tDPS. Her EHP would also increase by about 100k, as well as her actual HP by around 9k.
For some reason I cant change the text back to the color its supposed to be on the following paragraph.
http://www.d3rawr.com/d-sniAc Here is the profile with two sets of gear on a barb. Set 1 is her current gear, unchanged. Set 2 is her gear with those 5 items that I mentioned replaced. The dps for set 1 is a little bit off because I cant turn off weapons master for 1 set but not another. This shows a lot of information, but on the right side column under the attributes box there is a tab called "tDPS and life gained per second" which shows true dps as well.

Just as a good metric for weapons, a mace with 905 dps (500-1009 damage range, 1.2 speed) with the same exact stats as your current mainhand gives you almost 7k more dps (with shout up).

These two goals will have you comfortably farming mp3 (though neither fast nor efficiently). Even with the improvements that I mentioned, it is still best to either farm on MP0 or MP1 at your gear level both in terms of efficiency, and ease.

Dropping the 3 piece IK bonus wouldn't result in a huge survivability decrease as long as you keep the 2 set bonus (you can even grab those IK gloves for the damage decrease they offer). Chest/Gloves is the best 2 set for IK due to how much better your choices are for the helm, belt, and boot slots are. If you want to run the 3 set bonus, I would go with IK boots so you can still keep the Witching Hour and Andys/Mempo.
I also urge all Barbs with over 450 AR to drop impunity for Overpower- Crushing advance due to the extra damage along with the huge survivability. With enough crit chance and attack speed, you can keep it up 100% of the time. As 2x1H hota, you can swap unforgiven for bloodthirst passive for a good amount of LOH, as well as the ability to make up for the loss if you get a witching hour. You can also swap the bash rune for any other bash rune due to the high attack speed of this spec giving you tons of rage really fast.

Set 2 shows what would happen if you upgraded to the lower end of what I suggested: andy's helm, fire walkers, a simple trifecta ring for left slot, right ring changed to a slightly better one for you, 1h weapons (very good EF and a sword), a neck with better str/vit (which should be really cheap to find similar on the AH), mid tier IK gloves, lower end mempo, and the legs you mentioned in your post. Set 3 is the same gear as set 1, but with the same 1h weapons from set 2, and decent fire walkers (that should cost under 10 mil). The dps numbers include Battle Rage, and I swapped impunity for Overpower-crushing advance (this applies to all 3 sets) to show EHP changes. I also gave you bloodthirst to show how powerful it is as a healing ability. Adding Inna's temperance pants would add around 8k more dps to set 2, but would lose you a lot of str and vit. The second set could be much better, but you get a rough idea of how much the changes effect your character.
Though the dps difference between set 1 and 3 is only 4k, and that you lose like 3k hp, the difference between your life gained per second (while hitting enemies) is 3k more for set 3. The DPS gain (on paper) is also pretty far off from what it would actually be due to the inability for the site to factor into the fray into the frequency in which you can use HOTA. The best metric that I can use to measure the actual dps difference is the tDPS tab on the right which calculates the dps of the sprint tornadoes + whrilwind damage. Set 1 is 430k, set 2 is 610k, and set 3 is 493k. WW dps is very different from HOTA dps, but it should give you a good idea of what the diffrence is between 2h and 1h weapon specs. The difference in attack speed is extremely important for both HOTA and WW barbs, and generally outweighs the higher top end damage output of 2h weapons. With your almost 50% crit, Overpower-Crushing advance should almost always be active on you, even without higher amounts of attack speed. Seeing as you have 8 seconds between when the 30% reduction falls off, and the end of the cooldown, chances are that you will land enough crits in that time to reduce the cooldown enough to have it up 90% of the time on the lower end.
Sorry for the huge post, but I really havent dived deep into someone's profile in a long time, and I dont mean to steal this away from the TC either.

Bottom line on finding an upgrade versus buying one: Probably wont happen. The way the market is right now, getting upgrades at lower gear levels is really cheap. It is more worth it for you to farm alkizer runs (or whatever run you prefer) for gear/gold to use to buy an upgrade than it is to actually try to find an upgrade as a drop (at least for times sake). For your time (and barring the gods of RNG), it is better spent doing runs to get gold/that occasional good item drop for upgrades rather than just trying to find one. As an example, the last time I actually found an upgrade for my barb was 2 weeks ago... the last one before that was before MP dropped (hell probably before even 1.2 dropped). After the initial gearing period, you will be very lucky to find an item that is a really nice upgrade, even with the improved drop rate.
To further expand on LS versus LOH, its actually best to get both stats if you can afford it. Without a link to your profile, I cant say what pieces are in more dire need of an upgrade over the other. For example, I run 8.8% LS and like 300 LOH right now (110k dps), but back when I was at 63k dps, I ran about 1200 LOH and 4.6% LS. There is also playstyle to take in to consideration on whether or not LOH is better than LS below 65-75k (which is usually the breakpoint where 900 LOH < 5%+LS). If you tend to use your actual whirlwind along with your tornadoes for damage, than LS is pretty good for you. There is no definitive DPS number where LOH becomes magically better or worse. The determination is mainly made by factoring in crit chance, crit damage, attack speed, and strength. You can use d3rawr to enter your barb's gear and using the tDPS tab on the right, see how much LOH = 1% lifesteal for your gear). The "magic number" that you want to hit is basically the point where the value of LOH is less than LS to the degree where making up the difference is a detriment. To put it more simply, once getting 2.5% is more worth getting that slight upgrade to LOH, then you hit that level. If you dont want to use any sort of online stat calculator, the only real way to find this out is trial and error. Like i said before, roughly speaking, at around 65k dps, the value of lifesteal begins to overtake LOH in terms of overall healing. Remember that LS procs on ALL DAMAGE rather than having a proc coeffecient like the sprint tornadoes do for LOH. 65k dps is also the point at which many of my barb friends begin getting more aggressive with WW, and use it more to damage rather than as a way to clip through enemies. WW only benefits from LOH for the first tick of damage, while LS is generated from every point of damage done.
Now this part is very important:
What this should say to you is to try to build a set on balance rather than getting all perfect items right now. I was exactly at the spot you are at a little while ago, and what I did was build my set based on rounding out my gear, so to speak. Depending on your budget, you may want to get those gloves that have str, AR, crit chance and CD, but have no vit. You may want to get that neck that loses you 3k HP, but gives you 150 str. You can make up for the losses with other pieces of gear. The tryhard budget barb video actually illustrates how you can put together a set of gear by having pieces missing one or two stats that would make it otherwise godly.
As for upgrading big versus small, its mostly on a case by case basis. It really depends on what slot you are looking to upgrade, and the item in the slot itself. If its a neck with like 170 str, 100 vit, AR, and +armor or something, then it would be very worth it to spend a lot of gold for one with crit chance and crit damage (or attack speed). What I can say about lower gear levels is that since your strength isnt very high right now, it should be your main concern as long as you can keep most of your other stats. Right now losing crit damage wouldn't be quite as damaging if you could gain a decent amount of strength. More to the point: at your gear level, going big on upgrading the worst items will give you the most overall benefit right now. I know that seems sort of common sense to say, but rather than upgrading X,Y,Z slots with medium upgrades, you would see a very noticeable difference if you picked up an upgrade for the worst item at a higher cost. At MP0/1, you can afford to drop some HP/AR for dps, and probably should consider doing so as dropping (or lowering) those defensive stats makes for a much cheaper and bigger dps upgrade.
Now as you are farming MP0/1, you can lose quite a bit of HP in favor of DPS as monsters wont hit you very hard with that level of AR/HP. Dropping vit in favor of very high strength/AR/crit/critD/AS will net you an overall huge upgrade. Bloodvaga is spot on when he talked about moving into the 100k dps range too defensively. You can likely drop down to 35k hp and see not a huge difference in survivability if you keep that LS/LOH as high as it is right now. Dropping 7k hp would likely allow you to get your DPS up by a whole lot, more than 20k pretty easily depending on how much vit is on the item that you are replacing. As far as 1h vs 2h goes, a 2h WW barb requires a TON of gear to be efficient, and frankly isnt worth building to unless you have a serious bankroll. Now I am a somewhat strange breed in that I am only just now beginning to worry about getting attack speed rather than trying to get it all along. Now i am going to get mathy here, but unless you can get to an attack speed breakpoint (the point where your WW/tornadoes will tick 1 extra time), I would somewhat urge you to put it lower on your priority list. For this reason alone, I use enchantress rather than scoundrel as my follower due to the fact that her attack speed buff puts me beyond that breakpoint.
Specific legendaries that are cheap for good stats (at your gear level):
Lamentation belt: Seriously a great belt if you can afford to either drop vit or AR. On US servers, you can get one with 180+ str, 80 vit, 2.7% lifesteal for under 1 mil, and they even come with 1% crit along with a bonus to an ability.
Unity: high strength, 4.5% or more crit, + damage affix, and LOH for really cheap if it doesnt have crit damage, vit, or AR
Strongarm bracers: only if you must, as many rares are better, but these usually roll really nice and are dirt cheap again. High strength roll, % life, 3%+ crit.
Fire Walkers: EASILY one of the most underrated items in the game. Capitalize on this as they can have ridiculous stats (though not ice climbers). I got my 160 str, 140 vit fire walkers for 500k. They automatically come with fire resist and 12% runspeed, which is very nice, and the extra 4-6k ticks from the fire trail adds up quickly.
As for specific to slots, at your gear level here is what I valued when I had similar gear to yours(spoiler tagged to save space):
Helm: 50+ Str, some vit, 45+ AR, 3%+ crit chance, socket (ones without sockets are dirt cheap though and have better stats)
Neck: High (130+) str, 50+ vit, 8%+ crit chance, LOH (crit damage or +dmg if you can afford to drop LOH)
Shoulder: 150+ str, 80+ vit, 55+ AR, and either life% +armor or phys/fire resist
Chest: 80+ str, 60+ vit, 2-3 sockets, 55+ AR (these days you can find ones much better than the stats I listed with only 2 sockets for really cheap)
Legs: Basically the same as chest except 1 socket and higher vit than str (2 sockets are really expensive)
Belt: 180+ str, 60+ AR, 2.5%+ LS, and basically any other stat that isnt +health to globes
Gloves: 80+ str, any vit (or none depending on if you want crit damage/AS), 40+AR, 9% crit (8% if going for crit damage)
Bracers: highest strength i could get, 40+ AR, 5-6% crit (adding vit multiplies the cost at least 10fold)
Rings: +damage (a seriously underrated stat), 100+ str, 3%+ crit, crit damage/AS if i could, if I couldnt get crit damage/AS, vit/AR, and MAYBE LOH depending on the cost.
Feet: (this was before the price for firewalkers plummeted) 120+str, 100+ vit, 10%+ movement speed, and AR if it was in budget.
Weapons are a whole other beast.
MH Weapon: At your gear level, the best choice would be to go for the highest dps mace/axe you can that rolls crit damage and MAYBE str/AS. I know that it feels wrong to possibly lose a socket, but if you can go from an 830 dps 100 str 40% crit damage socket weapon (with a 60% gem) to a 1k+ dps weapon with any str, 60%+ crit damage, and possibly AS, you will see a HUGE difference in the damage of your tornadoes and the whirlwinds themselves. I personally am a fan of maces as they have the better damage range (the 515-1064 damage part below the dps number). Depending on your gear (again since your str is low, I would probably prioritize getting that up above getting new weapons), your most expensive upgrade will be here. If you can get your strength up, splurging here is a really good idea as the sprint tornado ticks are based on your mainhand damage only.
OH Weapon: Stats. Nothing else really matters until you begin using WW a lot more. You want a sword or a dagger offhand, but daggers are the way to go unless the sword has enough attack speed to put it above 1.5 weapon speed. For individual stats, get the highest str, crit damage, lifesteal dagger you can with a socket. You can swap LS for high LOH if you want, but once you get above a certain threshold (determined by gear), LS is better.
TLDR: The easiest way to know how much a given increase of each stat would benefit your DPS, use something like d3rawr.com or d3up.com. Those websites both give you specific amounts that increasing any offensive stat would increase your dps. d3up.com is great for determining what item is giving you the least benefit in terms of EHP and DPS which is very nice, while d3rawr.com gives you in depth data for dps (such as what your ACTUAL dps is with tornadoes, and also how much LOH is worth 1% LS). At lower MP levels, you can sacrifice a lot of vit/AR for dps as enemies dont hit very hard, and should die too fast to damage you too badly. It is more worth it overall to upgrade your worst items first, even if there is a bigger upgrade for a better item because those upgrades will be cheaper, and have more of an impact.

If you swapped her mainhand spear with a mace with the same str, IAS, dps, socket, but with no LOH, and 50% crit damage, she would gain 6100 dps. If you swapped her offhand spear with a 738 dps dagger with 115 str, 2.6% lifesteal, 500 LOH, and a socket (with a 70% gem in it), she would gain 5400 dps. Even though she would lose a net 180 LOH and .3% lifesteal between the two new weapons, she would end up gaining 400 more life per second (not including the life regen from the shoulders) because of the difference in her damage overall. The dps gain is in large part due to the 10% bonus crit that she would get from swapping to weapons master and having a mace in her mainhand. With above 45% crit (after battle rage), WW barbs do not need animosity due to how fast they gain rage (especially with her having 55% crit now that she would have weapons master).
If she were to swap the shoulders for ones with similar(or more) str, no +armor, no regen, maybe slightly less AR, but with at least 26 vit, she would net gain survivability (26 vit is equivalent to the +265 armor in terms of survivability). For another big upgrade, you can grab her an IK helm that has on the lower end of strength (under 100 ), 5% crit, 10%+ life %, and a socket for extremely cheap. You can also just find a similar helm (that just isnt IK for probably under 1 million and may even have AR or vit). The nice thing about getting the IK helm is that you not only get the 2 set bonus (netting you 60 AR for free), but the helm also offers 5% less damage taken from melee.
I uploaded her character to d3rawr and swapped in the gear that I suggested with around the stats that I said. Set 1 is her normal gear, with nothing changed at all. Set 2 is with a new helm, shoulders, bracers, and the two weapons. With those 5 items, she would gain 20k damage which is actually gaining 90k true dps. True DPS is the actual DPS that she will be doing with her sprint tornados + the whirlwind damage. She goes from 158k tDPS to 249k tDPS. Her EHP would also increase by about 100k, as well as her actual HP by around 9k.
For some reason I cant change the text back to the color its supposed to be on the following paragraph.
http://www.d3rawr.com/d-sniAc Here is the profile with two sets of gear on a barb. Set 1 is her current gear, unchanged. Set 2 is her gear with those 5 items that I mentioned replaced. The dps for set 1 is a little bit off because I cant turn off weapons master for 1 set but not another. This shows a lot of information, but on the right side column under the attributes box there is a tab called "tDPS and life gained per second" which shows true dps as well.
