Drilled are good because they dissipate heat more effectively, but at the cost of weakening the rotors slightly, which may lead to cracks or warping. Slotted are good because they efficient at shedding dust and rain, though at the cost of shortening the life of your brake pads. Look at fcpeuro.com. They're cheaper and just as good IMO.
Upgrade to the 302's in front and the rears are the same in size.
I just replaced my brakes with the upgraded 302's and SS lines in the front and went for an OEM replacement in the rear. With ttah sizing, the car no longer feels like the brakes are too small, which is awesome.
Personally, I would stay away from cross-drilled on the street. I Have used ATE's slotted design before, but also didn't like it. I recommend getting a good set of OEM or OEM+ rotors (Brembo, Zimmerman coated) and a good pad combo (I'm using Akebono's and love them, have tried EBC in the past with mixed results, OEM has a LOT of dust).
