Can anyone recommend a good book/instructions on basic body work?

Last month I went skiing to Alpine Meadows.  A day after I came back I
noticed the dent in the right rear corner of my Syncro.  Some paint came off
and the bumper is slightly bent.  Someone must have hit me while I was
parked at the Alpine Meadows parking lot.  I'm just wondering why I didn't
see it earlier.  Anyway, I can see slight traces of rust forming where the
paint came off, so I figured it's time to do something about it.  I went to
a body shop (friend of a friend of mine) and got an estimate: $450.  Big
number for a little dent like that!  $450 is not in the budget right now, so
I'm thinking of trying to fix it myself.  At least I can just touch it up
and deal with it later.

Any advice would be greatly appreciated.
