yeah, i didn't mean to offend you or anything, it's just that there's a certain level of auto knowledge you need before embarking on this kind of thing.
bodywork, without reshaping doesn't need much, a flap wheel and a drill gets rid of rust ready for filler and primer. sandpaper is good for that too, but takes longer and requires more energy.
for engineering work you need:
screwdrivers
socket sets
wrenches
torque wrench(es)
hex keys
piston ring compressor
flashlight
that'll probably take care of most of the stuff. you may need other tools that i can't think of.
i've actually got a list here of tools i'm going to buy (when i have a spare $2,000 laying around..) but a lot of that is stuff you won't need (metric things, torx sockets etc..)
what's your budget for tools?
