Well hopefully someone will step in here and offer some additional advice and guidance. However, with as varied as those symptoms are and the systems affected Im wondering if there is an issue with the ignition switch. Purely a guess at this point as GM runs a lot of power to the accessories and such through the switch and when mine went bad I had several things that were not working as they should.

But keep that in the back of your mind for now as you have a lot of systems being affected. If not for the ABS and No Trac condition I would point more heavily to the ignition switch but the ABS and No Trac light would lead me to believe there is a bad wheel bearing. It could possibly be you have more than one issue.
