I think this has to be the work of a desparate young Bush hater. Probably associated with one of the sleazy Soros funded organizations.

I think if an adult higher up in the food chain was responsible, the forgeries would have been more accurate (use a typewriter or at least inspect some period documents and choose a font that is close). Even if it was Rove (unlikely) he would have made good forgeries so that he would he sure CBS would take the bait while holding something that would prove them false as soon as he had sucked as many as possible into his trap.

As pointed out elsewere on this thread, 60 minutes was trolling for disgruntled national guardsmen (through moveon.org I think). I bet they were trolling for Bush AWOL dirt through the same organization and happily accepted documents produced by this person since they supported the conclusion they had already concluded was true.
