I would switch your meta the 21 agi one which only requires 1 blue gem to activate. I'd put the nightmare's tear in your blue chest socket instead of that Arp+Stam. Agi to cloak is better than Haste to cloak. I wouldn't socket for Crit either. At your gear level I would probably stick 10 str 10 crit in yellow sockets, and armor pen in red sockets till you reach 722 rating (softcap w/ your NES). I would also be on the lookout for better ArP gear like Gatecrasher Gauntlets + Vengeful Noose from the Frost vendor.
You have wiggle room for hit, as you only need 164, keep that in mind when looking at upgrades.
Your biggest upgrade would be Ramaladni's off of Saurfang 10. That would let you get rid of your expertise gems + enchants or that trinket. I don't care what people are telling you, I think you're geared enough for ICC10.
Do you have a DPS neckpiece?
I'm not really a fan of Anger Management + Unbridled Wrath. I'd take points out of that and just go for 2/2 Booming Voice and 4/5 Commanding Presence. Longer and more powerful shouts > a few extra rage here and there when you're already going to be hitting so hard it doesn't matter.
EDIT: Looks like you erased your post?
