Yeah no worries about time mate, I'm going to have to wait a few weeks while the laptop is shipped hehe.
Funnily enough I'm doing the exact same thing; getting RAM and OS from OCUK and running Vista via bootcamp.
AFAIK bootcamp comes with all of the windows drivers on it already. However there were issues with it not having 64bit drivers for the wireless net connection and things like the iSight.
Everything works fine in 32bit Vista, but last I heard there was still a driver issue with 64bit.
Sorry you have to be a guinea pig but thanks again.
