Email me if you'd like specifics/pictures (tbaranek@earthlink.net) I've done 9' ceilings...but I'd go 10+' if I could (for a lift later on). I did NOT do any special conduit for wiring. Lighting-I've tried (in the past) to light the heck out of my garage (like a paint booth)...but never what I wanted. So, I went with low profile, aim-able halogen eye-balls (as I move things around I can re-aim as desired). And I got a couple of good 500 watt double shoplights on stands to do the work. Maybe plumb for air compressor. I two-part epoxy'd the floor, after it cured but before I stained it with wear/tear. Cabinets from Home Depot/Lowes. No drain. Internet (either cable or wireless from the house). I did not do but maybe a TV cable.
