Premiere Pro will allow you to unlink footage and when you do, you can choose to delete the footage from the drive. So as you review each clip, you can decide to keep or throw it out. I recommend taking the time to do that. Perhaps you could use two PCs to capture. Rent one if necessary. Do an hour or two on one, the switch to the other. That will allow you to capture on one, and throw out clips on the other. That should maximize your productivity over the weekend.
As for special effects, you need to decide. If you are going to color correct your shots, you may want to use 10 bit. If not, then 8 bit is fine. It is really up to the footage and the editor. There is no right answer.
For 24 vs 23.98, I believe that the F900 can shoot either. Which did you shoot?
It is easy enough to separate the audio from the video if you so desire. In fact, I often sweeten the audio in Soundbooth so it ends up a WAV file anyway.
My personal opinion is that you should change to CS3 before you get started.
