For the OP, read Mek's article on resto shamans - it's a great read, and talks about how you'll want to get SP, Int, Crit, and MP5 to a certain balance point, before going for haste. It also dips into varying your healing strategy a few different ways, depending on the situation.

What Embermoon said.

I have to agree with Barawr though, even when we raided Ulduar with half the raid dying due to overload at the start, i didnt really find mana as an issue.
Pots and totems are there to be used, why else bother taking the talent/making the pots?
