Here is a comprehensive list of decent Macros to make, nifty UI addons and whatnot that our guild Main Tank (and probably most competent Warrior) uses.

If you need help Tanking in any real way, Geekz would know quite a bit (and I do too). I assume you know that Sunder Armor is your major Aggro holder while Revenge works very well also. Taunt is used to get mobs off of other characters, and just get back to work on generating Hate. I also hear that Heroic Strike actually generates more than normal Hate, so if you need a Rage dump, go for it.
