New X3 Service And Warranty Options?

Good morning. Sometime between tomorrow and Saturday, I'm taking delivery of my new X3 (silver, 2.8 XLine, lots of options). When I meet with the dealership finance manager, I expect that he'll promote after-sale service options like extended service contract, tire warranty, etc. Which of these do you think is worthwhile and cost-effective?

Thanks,

Dan.
