Unfortunately, the best he can do with all this you've got here is try to game out what gets done after the Inauguration. A lot of this looks reversible. He's not the president yet, so he doesn't have the authority to do anything beyond the normal powers of a senator. Once he's president, he can overturn unilaterally anything Bush has done unilaterally, as we're seeing with the executive orders. WHEEEEEEEEEEEEEEEEEEEEE!
