I just found a fix for the "GetPrimaryTalentTree"-Error on Moonkins:
Just replace "GetPrimaryTalentTree" with "GetSpecialization" in the StateModules.lua (there should be 3 lines with this function).
For the Spell-ID Errors just open Defaults.lua, search for the spell ID and check the spellname on wowhead. Replace the false ID with the new one from wowhead. (Just check the url of the spell, there you will find the id!).
