One absolutely awesome thing about feral bear tanks, is the fact that pvp gear is actually VERY nice in lots of slots. Honestly full furious (which you can buy with honor now) is more than a fine start. And if you look at many bear tanks, you'll see that even with access to pve gear, the high stamina on a lot of pieces (particularly hands and legs) make them quite desirable.

Sure farm some heroics and fill some slots. But also get on random arena team for points, and in 3 weeks buy yourself the relentless legs and hands for arena points/honor. There's actually quite a good gearing guide on the official forums strangely enough.
