Elitist Jerks is a little off for shaman for some reason.
Believe it or not the oboards have decent guides for all three specs on the shaman forums, stickies right at the top.
For resto i would suggest the two at the oboards (Jynus' guide to raiding and the fresh resto one, can't remember the name) as well as
Lifeingroup5.com. It's a resto shammie blog and he has some extremely helpful info there
