Theorycrafting

Hi guys

I want to learn how to start doing dps/threat simulations, is there a way or a website where i could find the spell and coefficients formulas related to 3.3.5?

Thanks in advance.

P.S. -> Lets talk about Theorycrafting thread in general.

I'd get the DrDamage addon for spell coefficients. It's an invaluable theorycrafting tool. Wowwiki should also have plenty of spell coefficients and whatnot.
