Shuld i stay as Resto Shaman or shuld i go for a dps cl?

Do what makes you happy, dude. If you liked DPSing on that shammy, do it. I don't know what the gear is lookin like for Wrath, which cl is going to be better, but i'm guessing they're all gonna be pretty balanced after the initial million patches. Just remember, though...its harder to get a Pu as a DPS than it is as a healer. But if you're running with your guild, I don't think you will have much trouble getting a spot as DPS. They'll find another healer. And if they get mad at you for going back DPS, who cares? Tell them to stuff it.
