What's more important for ZA is who the other tank is going to be. For Nalorakk (Bear), Halazzi (Lynx), and Hex-lord Malacrass, you'll need 2 tanks. For the other three bosses, you only need 1. If you bring a prot warrior or a tankadin, one of you is going to switch to DPS on 3 of the boss fights. Who would you rather have as DPS, a kitty druid, or a prot warrior in DPS gear?
Other than that, your health is fine, but your armor is a little low. I'd replace Garona's with the Badge tanking ring, trade Staff of Natural Fury for either Earthwarden or Braxxis, and try to get the Cowl of Beastly Rage if your T4 helm isn't dropping. Those 3 together should bump your armor up to around 29k.
Right now, I'd say you can MT the bear and the eagle, maybe the dragonhawk. Halazzi if your healers are better geared than you. We stopped running ZA when we got into SSC, so we never cleared past the first 4 bosses.
