First a couple points: With the patch coming out today, there will be a significant influx of players, so the AH will see a major boost of stuff coming on, AND people BUYING items. Prices will likely be all over the map for a couple days, so you'll have chances to get some awesome gear for cheap if you get lucky timing.
From what I've experienced on the PTR, imho here's some general goals for doing well on MP7+:
Get to 100k + dps
Get 45k+ HP
Keep 600-650 resist (more is OK, but will come with a high price while gaining DPS)
Decent armor (forget actual value here).
Get 2.7+ Life Steal + 600-1200 Life On Hit. (can get double life steal and drop most of the LoH, but will be expensive on both weapons).
So, 100 million, when spent properly, can definitely get you to the above (I was able to get there with less than 100 million, but has taken alot of time and AH sniping).
Upgrades:
Swap +XP gem to +Life % gem in helm. You will likely be able to run MP 2-3 at the same pace you could run Act 3 in 1.0.4, so you'll gain 20-30 XP% from the MP2-3, and can get more HP from the helm (and then be able to replace the gems in your pants).
Get 2.7 Life Steal on one of your weapons while keeping close to the same DPS you show now.
On rings, keep similar stats to what you show (crit + resist + vit/life %) but Add either AIS, or High Average damage
On Amulet, try to maintain 500+ LoH and get high Average damange, high Crit %, AIS OR Crit Dmg, Single resist (this will take resist pressure off of bracers to allow you to go to single resist and get much higher dex + crit %)
Swap bracers to 150+ Dex, 5.5+ crit, single resist, vit.
Pick up a nice set of Vile Wards for shoulders: 170+ Dex, Vit/Life %, Double resist
The above is just my opinion of course, concerning specific upgrades.
The one thing I would REALLY recommend is laying out a specific plan on what to look for on what items (similar to above), then just keep a VERY close eye on the AH for the next few days for those items. You'll likely find some amazing deals as new items start to flood the AH before the market re-stabilizes.
