I don't know why people don't suggest this more often, but if you know exactly what gems you're going to use you really should search for a 6L correctly-colored corrupted chest. While I'm waiting for RNGesus to finally 6L my Belly, I sorted out all my resists on other gear and then just search for a chest like that with as much life as possible, and ignore all the other stats.
That said, I'd be careful with colors for that build. Damage on Full Life seems like a huge noob-trap to me. There's no way that gem is remotely comparable to alternatives like Cold Pen, Ice Bite, etc., especially against bosses where it really matters. I'd probably shoot for a GGGRRR chest, since I also think crit/crit mult gems are pretty meh after the nerfs.
