I've updated the TODO a little as well as cleaning up the XXX markers.  The relevant ones are mostly just open questions on implementation tweaks, so nothing major.  Otherwise my goal is to finish as much as possible of the non-critical items before the beta.

Brett: Any opinions on priority for the non-critical items?

Also, do you have a plan in mind for "Python can function w/ find_module(), find_loader(), and load_module() removed"?  Do you mean comment out the deprecated methods and see what happens?
