will probably roll an ele, some questions now!

hi folks!
mostly everyone suggests an enhancment build for efficiently leveling.
is an ele/resto build much slower? (more time spending drinking?)
what is the rotation for leveling?
what talents can i skip buying from trainer?
how should i spend my talents if i decide to go ele?
(i would go enhancement, 1+shield, till 40. 30/0/21 then)
which race is best for pvp / which for pve?
is there a pvp bis list for elemental shamans?
got it:

thank you guys!
edit: ok, i could answer some of my questions by myself. pls correct me, if i am wrong.
