1: Divine Favor
2: Turn off CE/PA
If he's main tanking, CE is a necessity, but I don't forsee him doing that when there are builds entirely devoted to being a tank (that hit mid-70s+ unbuffed once M9 PrEs drop) that can do it much better.
PA is less of a necessity. It's a nice increase in damage, but if he's missing as often as you're claiming he might, then turning of PA actually increases his overall DPS.
