Use good insulation. I have used the 3/4 plywood thing but the sheet rock looks better. Get plenty of lights, I have 3 twin 8 footers in the front of mine and still not enough. Lot of receptacles (on different breaker than overhead lights) I will build benches that will hinge off the wall and sit on legs that are removable, this makes a lot of bench space and when your done with the bench it pivots up out of the way (also keeps it clean, no clutter sitting on it if its up).
