Put a str/hit gem in your gloves and you should be closer to hit cap and the forging should put you right around exp cap.
Crit and haste are close enough in value now that, on a piece with crit/haste you can just reforge whichever there's more of. You should also put 50 str on your gloves.
As far as you replacing one of your tier pieces if you get the legs off shannox, the helm from alysrazor is the better offset choice for alliance than the chest is, so I'd go for that. You should also get the VP ring to replace the pvp one, since it has worthless resil.
You should also move points from arts of sacrifice into EfaE (you can keep one point in arts if you want the snare removal and have one in EfaE, otherwise move both).
