brake parts ( Oreilly or Autozone )

[a_magoo]

I need a rear rotor and a new set of pads for my 96 formula. What do ya'll recommend? I'm not sure what brands from Oreilly are like. I saw that the AIMCO rotor from is good but should I get one with a lifetime warranty. What pads are suggested for my car? I put the cheap non-metallic or wahtever on the front but makes horrible brake dust. What pads should I go with to reduce that but not spend an ass-load of money? I'm a college student with little to spend and need brakes, so any advice would be appreciated.

Thanks,
Aron
