Weapons is something you need to fix even if you spend 0 gold on it. Get an offhand with less DPS but more stats, specifically life steal in addition to the LOH. Main hand can have less stats (say, no crit dmg or no socket), but have a lot more DPS. Your character screen will show less DPS but your tornadoes will hit harder and heal more. Consider a mace rather than mighty weapon for main hand.
I'd get at least 1 level higher of experience gem in helm and emerald in offhand, and then start looking for chest, pants and/or boots with more vitality with the rest of your gold. Then, if you have anything left, consider a stone of jordan - You might lose 6% crit, but you will kill elites much faster, and when you farm at a proper MP level elites is what you're actually stopping to kill, while when you do ubers and key runs at higher MP elites is what gives you most trouble, and for them you'll want to maximize your DPS (which will increase your life steal, which should be closer to 6% or 9% if you push even higher MPs and use bloodthirst).
