Is there a schedule available?

I have just bought a 2000 A8 4.2 Q LWB. It has done 59k and the on-board check tells me a service is due. 1) Is there a schedule available of things to do
2) Although they appear little worn, I think the front brakes discs may be warped - a shudder can be felt through the car under breaking. I am perfectly happy with the stopping power of the brakes i.e. not lusting after AP Racing or even drilled / grooved, but wonder what is proving to be the best/most reliable make of standard type disc / pad. Any help from Forum members appreciated.
