First goal get your CTC to 102.4%, thats get your dodge% +Parry%+Block%+5 to equal 102.4% or slightly above it. Ideally refored any non tanking stat to mastery, and try to keep both odge and parry ratings about equal. if a peice has parry and dodge refre whichever will give you the most mastery.
Gear wise, Chain run LFR and LFG for the valour points and pick up some 397 valour gear, Trinket wise get some static Mastery ones, DMC: Earthquake is a horrible trinket. The Black Heart form ToC normal is a better trinket and thats an ilvl200. the valour trinket is good as is the the one from the Tal Barad vendors; Mirror of broken images.
