I am interested in bench layouts as well, as I am in the process of building one in my basement.
So far the 2'x6' bench with the 18" by 6' shelf above it is done.
I wired in an outlet below the bench for a tumbler and maybe a space heater. Also wired one on the bench along with a powerstrip. Picked up a set of the under-cabinet mini halogen lights (used in kitchens) and put them on the underside of the shelf. There are 6 lights in the pack, and they work pretty slick, but they are only 10w bulbs. I will probably upgrade to 20w bulbs as I could use a bit more light but they aren't too bad.
Still looking for more ideas...
