www.goodtutorials.com and www.tutorialized.com are good for photoshop tuts. I also use them for Illustrator and 3D studio max. www.brushes.obsidiandawn.com and www.Brusheezy.com are good for brushes.
My fav PS tutorial site is cgarena.com unfortunately most of the tutorials is not for beginner, you should already know how to use brush, dodge, burn, filter etc. It has jobs/contest section for 2d and 3d artists.
