Tanks and You.

I know I only put up the specs for dps in raids, so I'm going to show you the talents for the tanks.

Death Knight- Go Frost, its the best tanking spec of the three trees, which obvious if you look at it. Rotation for abilities should be Icy Touch, Plague strike, Pestilence, Blood Boil, then Howling Blast, Frost Strike to dump your Runic Power. Works out rather well for AoE tanking. With the new Rune of the Stoneskin Gargoyle, 2h tanking is the way to go.

Warrior- Apply your 5 Sunder Armor, Shield Slam, Revenge when it pops up, Devastate, then Shockwave.

Paladin- Keep your Holy Shield up, Shield of Righteousness, and use Judgement whenever possible(Seal of Righteousness). Pull with Avenger's Shield.

Simple right? That should help you out a bit.
