It sounds like the dealer was going to replace all your pads, all your rotors, rebuilt your calipers, change the fluid, etc.
I just finished putting front rotors and ceramic pads on my 2003. Old rotors were a bit warped. The new rotors were $40 each and the pads were $65. I did the back pads last fall, they were $45.
People go overboard when they do their brakes. Unless you are having problems I would just drop in a new set of pads and be done with it.
