Z4 Roadster (E85) 2006 3.0si Inspection coming up

My 2006 3.0si has an inspection coming in 800 miles according to the instrument panel indicator. That's fine. What should I expect? What will be inspected and how much is the inspection likely to cost? Anyone have any experience with this they would care to share?

Also, since there is no dipstick and the only way to check the oil is to rely on the instrument display, which says the oil is O.K., should I be worried that I have gone 7000 miles and there is nothing saying that the oil should be changed? The owners manual says that the computer will tell me when to change the oil based on previous driving conditions and habits. I'm really not O.K. with that. I'm thinking 5000 miles and change it. This car is driven tenderly. It may be 10000 miles before the computer finally wakes up.
This is my first Bimmer and I don't want to mess it up.

Thanks for any input.
