5 Things I hope Revenge of the Sith will Resolve

Here are five things I hope Star Wars Episode III: Revenge of the Sith will resolve (besides the usual 'How did Yoda end up on Dagobah', 'How did Leia end up on Alderaan', and 'How Obi-Wan ended up on Tatooine' etc etc."

1. We know the Clone Troopers become the empire's stooges, but how did the X-Wing end up with the republic while the Empire ended up with the dorky looking TIE fighters?
2. How did Anakin manage to forget that he BUILT C-3PO in the first place?
3. Judging from all that jet-setting and fleeting secret meetings that always seem to be interupted by C-3PO in the Clone Wars cartoons, how the heck did Anakin and Padme actually find time to er... make babies?
4. Exactly how old is Chewbacca and what the heck is he howling about?
5. Considering R2-D2 has been around from the very beginning in The Phantom Menace until the very end of Return of the Jedi, how does he keep himself rust-free, and why isn't his processor obsolete by ROTJ?
