I recently got a full set (front and rear) of Rotex Gold pads from
www.buybrakes.com for $112 shipped - I don't know if that price is still in effect (check the home page because they had a $10 off code listed).
I ordered a full set of black anodized cross-drilled and slotted rotors for $251 from
www.brakeperformance.com - they are supposed to be in this week. If all you want are plain OEM rotors, they are a lot cheaper. I did a lot of checking, and it seemed that they all were fairly close in price. Some offer free shipping which can save you some $$$.
Don't forget to get brake lube and anti-sqeal compound - I got both at Autozone.
