As for gold? If you want to do pure gold farming, invest in a Gold Find set, and destroy vases in the Inferno Royal Crypts. It can yield pretty good gold/hour.
My stats were about as follows: 865 Resist all after War Cry with Impunity 8,278 Armor after the Enchantress' 15% Armor Buff (It's a bit low) 52,000 HP Using a 686 LoH, 168 Vit, 683.4 DPS 1Hander, was running about 6,931.02 DPS for most of Act 2.
The shield I'm running with is a Blue "Chromatic" "Of Valor" with 77 Vitality and 56 All Resist, 18% Chance to Block with 1960-2794 Block Value.
Here is an accurate screenshot of the stats I had when clearing all but Belial.
Personally, I lucked out and found my Weapon. So I didn't have to spend 'too' much. Another thing, is Life on Hit doesn't necessarily matter outside of when you have to take on a couple large mobs with nothing else to get Revenge on. Life on Hit really comes into play on Bosses.
But overall I probably sank at least 1.5 million into the rest of my gear. Ideally I picked up Str / Vit / Resist All, optionally replacing Str with Armor, and ideally getting as much Armor as possible as well.
Did all of Act 2 EXCEPT Belial
For Belial all I did was switch Earthquake for Ignore Pain with the heal rune, and once I transitioned into P3 (where he transforms, and the background turns green) I changed Charge for Leap with Iron Impact.
I did Act 2 pretty safely, had a couple packs that I had to skip, due to just being Shielding as well as other annoying affixes. But I safely carried a 5stack NV up until Belial.
