I am inclined to agree with Drae on the fire totems, not worthwhile talents in most situations.
As far as the total build it really depends on what you want to do with it, PvE, PvP, raiding? Also keep in mind that while most non-raid PvE builds do not currently go past Elemental Mastery the changes in 2.3 are going to make Lightning Overload essentially compulsory.
Anyway, post back with more info and I'll try to answer your question.
