One big thing that helped me was snagging a Tyrael's chest piece. The stats on it are solid and you can snag one for 20m or so. It allows you to get rid of the lacuni, get strongarm or something else that gives a large str/res/crit boost and all the dmg to demons, movespeed and resists on the tyraels.
Also i highly recommend looking for pieces that are +armor or +life%, it's often the last thing people search for, but I found that I was able to offset vitality on gear pretty much by searching for life %.
