i wrote this a while back. It might be useful to you
i will add that the plater addon is very useful, nearly mandatory, for tanking. it tells you which mobs you have aggro on and your threat status on specific mobs. when you are trying to gather and hold a pack, it shows you which ones need more love.
fwiw: i have gotten 5 of the 6 tanking classes to 2-2.5k rating at some point in DF, with the presently ironic exception of brew
