I would start by hitting ebay and getting a service manual.
As easttxss points out, I think you will need a tool which can communicate with body control modules. There are various clone tools available. Some of these will do SPS programming, although I am not sure about VIN delete and relearn.
Is there obvious damage you can report to us? Like underhood and interior, particularly the instrument panel and steering wheel?
I would try to find out what happened to this car. I would not start taking things apart without more information. Hate to open up a steering wheel only to find you have a bad module above the brake pedal which is much easier to get to.
