1. That one is up to you.
2. If this is a street driven car, that's way too much gear.
3. Why not just have the car re-tuned?
4. Stock or aftermarket? If aftermarket, get a chassis mount bracket.
5. You'll need a new one for any of those transmissions you listed.
6. Radiator should be fine, but you'll want the biggest tranny cooler thet B&M offers.
7. ?
8. Check out TCI
9. Stock rear or no?

As for additional info, check out the sticky at the top of this forum and the manual trans forum on swaps. I added alot into one of them when I did my swap. Plus there is some really good info in those.
