After weeks reading decide to post to ask for some help.

I have a 5 box (pally,priest) (Mage,Lock,Shammy). The question is I am approaching 60 and I wanna try to run all instances BC, before going to wrath. Is there are way I can make a rotation that all dps can be cast from one key? My talents will be fire mage, fire lock and enh sham. Any ideas, have you guys done something similiar?
