Enjoy, Rich! Watch your car.. the organizers are burning to drive a 987 around the track, or were the last time I was there. Probably just to show me that one can actually exceed 50 mph if driving the girl hard.
The crew at Bedford is great. If you want, spend the little extra (25 GBP I think) and get tuition. It's worth it, unless you're experienced already. The first few instruction rounds are actually free if you're a track newbie.
