The squeaking probably comes from your ceramic pads which are known to squeak. It's no big deal unless you really can't stand it, than you can just get a different kind of pad.

 

Thanks guys, the squeaking is almost non existent at this point, it was until the new pads adjusted to the rotors. I had another issue, that I realized when driving on the highway at high speeds, the car doesnt feel comfortable at all. I would figure that it would blow to 100mph, and cruise, but my fiance's '2.0T A4 feels better than the RS6. Any suggestions?
