Looks like you've got decent blue quality items.
My advice is simpel, bordering useless.
Just run instances after instances. There's a great deal of epic items that drop from heroics. And you have enough gear for clearing that. So get on it.
You should get a weapon chain (or other enchant, but that's rather cheap) for your weapon. You should get the helm "enchant" from the argent crusade.
Start getting rep with Kirin Tor, since you get a rather decent epic quality glove tank from that.
