Looking through the wheels yesterday, I'd guess the rears have 5mm + left and the fronts 3-4mm, so it's the fronts that need replacement. I haven't pulled a wheel to check the inners.
That's the first I've heard about not letting the pads wear thin to prevent rotor warp, I'll have to look into that. I always wait until about 1.5-2mm to change my pads and haven't had issues with warped rotors. As I recall, that's been the service limit on a couple of cars I've had, I haven't seen a service limit spec on these. The only warped rotors I can remember is my Mazda3 and those were the factory rotors with probably 150K on them.
