Run heroes. Wear tabards for rep / rep items.
Lookin at having mostly, if not all level 80 blues for going to naxx, gemmed and enchanted appropriately.
Theres also some BoE epics available on your auction house.
BOE's you can check the AH for or have made:

This site, is a strong reference when balancing your gear and looking for upgrades.
