I don't want the dolls behind the bar!
A lift is the best investment you can make, I think. A fout post will give you an additional parking space, but a twin post will make many jobs easier to get to. I've seen where people have "coffered" their ceiling to make additional clearance for their roll bars and windshield. I, and several people I know have less expensive lifts from "off shore" and they do the job without spending even $2K. Have a build party when you get one, especially since you already have the bar. They are simple to assemble an you should easily finish in 3-4 hours.
I've also found that an epoxy floor finish is well worth the money/effort. Certainly makes clean up easier and looks much better.
Lots of lights.
The more compressed air, and related tools, the better.
Lots of air movement, i.e. fans/AC
