Here are 2 links for you. The first is a rub I have used that's really good, and very basic. You can't go wrong with it, but it's not very unusual. Would go great on the BB.
The second link is to a good webiste of Steven Raichlen's and it has lots of recipes, and technique info too that might help.

Glad you've got someone to watch the smoker, sounds like a good dinner!!
