Class stats = X page?

I have a problem with alts...I'm about to get my third and fourth 70 soon with a ton of level 20s and 30s to follow... I keep getting the whole "X agil on a rogue = crit" and such mixed up with the warrior. Is there a page somewhere that lists what each stats do per class, and how many of the stats you need for a crit or mp5 and such?
