Tad, excellent list dude.
I had most of those in my head already do to for my garage. Got the compressor, haven't installed it. got the laptop with wireless card to go out there too (more so for music though
). fire extinguishers near both doors too.
im disapointed with the toolbox I got, the biggest and cheapest harbor freight had ($220 for 3 boxes) but it came dented, but the drawers really arent big enough for everthing I need. I may go get a craftsman, I saw them at about the same price for a little larger box after I got mine.
