as far as the compressor.. don't need it.. get some cheap electric tools, grinder and such.. at least at first until you find out how much you want to do. That is if you really want to do any of it. As far as the local School auto body, talk to the teacher and ask to see previous work done to cars.. if they can substantiate good work that looks origional and they are not planning to just patch everything but will drill origional spot welds .. what have you got to loose...
