In the Pics section of the Bali site here, I have published a diagram of the village setup, at least the way it was when I visited, although I don't think it has changed that much. Maybe that will help. Also, there is a map of the entire area around the club, so that you can see how the club grounds fit in with the rest of the tourist area.
If you have a preference for a room location, you can contact the agency where you've made your reservation. They can contact the club for you. (a preference is never a guarentee, but normally the club will do it's best to put you in the preferenced room)
