If you're looking for ideas on Warrior tank specs, I would point you to the link in my sig... Ciderhelm's builds have been working really well for me so far.

I've seen many people suggest having a pure healer + a support healer spec to help cover each other. My group now is 3x Chloro spamming their faces off with Lifegiving Veil up x3 and Bloom for the tank on round robin via ISBoxer. I still die on the tank or even wipe the party a lot, but I blame that on spotty internet lag - my heals are fine.

FWIW, I was facerolling Deepstrike Mines around lvl 25, and cleared Foul Cascade completely at 30; and I'm now facerolling FC at 32.
