Go to the thread "Basics of Basics" and click on the link. There you will find a "Basics" of buying tools. There is no list, but it gives an overview of how to go about buying what you need.
For metal work, a die grinder with a cut off wheel attachment is an absolute nessesity as far as I am concerned. And don't buy a wimpy one from Harbor Frieght (read the "Basics"

) they don't have any torque and are simply a waste of money.
A simple "heel" dolly and a nice flat faced body hammer are all you need to get started. Go to
http://www.covell.biz/ for the best prices on high quality body tools. His videos are more for the hot rodder wanting to fabricate things, but they are TOP KNOCH!! I have a number and I am telling you, they are entertainment for the family, my kids will sit and watch them. Ron is a true master at this stuff.
Of course a MIG welder will be needed.
