I just bought a Q7 at Stevens Creek about a month ago. I went with the paintless dent repair as well. I'm hoping I don't get any dings since I'm careful with where I park, but you never know right? I'm just considering it prepaid ding removal.
I'd talk to the finance person about the Audi Care. This happened to me as well. It costs $860, but the dealership charges a $100 premium. I'm not sure why, but the only dealership I've dealt with who does this. I got this adjusted by them...
I have no experience with the Wheel hazard, but it looked like there were a lot of exclusions. Seems to me there are a lot of "outs" on their end, but this is solely my opinion, not based on any personal experience.
