I've got a guitar I wired without a tone pot. I left out the capacitor on volume control so that when I turned down the volume is sounded like the tone was being turned down as well. A lot of people leave the tone on 10 all the time anyway so it won't sound odd if you leave it out.
I recently wired the same guitar with 3 humbuckers using a 5 way switch. It sounded OK but I found positions 2 and 4 can sound horrible with the wrong pickups, I think you'd get more verastile sounds using a single coil in the middle.
The 3 pickup Les Pauls use a 3 position switch and are wired:
Position 1 - Neck
Position 2 - Neck and Middle
Position 3 - Bridge
