More useful supplies - threadlock, dremel cutting wheels, foam tape, heat shrink, lubricant, electric motor cleaner, a TV, a TV remote, and something to shrink your heatshrink with.
The tools you should have - multimeter, razor blade/utility knife, Ruler/tape measure, various hex wrenches, various screwdrivers, a drill, a dremel, various clamps, vice grips, a vice, drill bits, a socket set, scissors, and a drill. I wish I had a drill press too.
AND if you happen to be into spud guns, your workspace should always have teflon tape, PVC cleaner/primer/cement, a PVC stockpile, cans of propane (7), masking tape, and an air compressor.
