Wow! I have been swamped with work today and had no time to check the threads. To answer your questions:
100 jury questions is unheard of! :what:
IMO it will take quite a while to argue these. Judges normally allow every one they possibly can, because they don't want the jurors to feel like they're being ignored. The ones that aren't asked will be for the same reasons as the attorneys' questions are sometimes rejected (irrelevance, etc). But the judge will go out of her way to "work with" the jury questions--e.g., if there is no foundation, she will ask the lawyers if they could establish foundation with additional questions; or if it has been asked & answered, she will probably just ask it again.
The witness does not get to preview the questions.
There will be additional recross/redirect if the jury questions bring up any new material.
IMO there is no way to guess which way the jurors are leaning without hearing the questions.
