Check the rears, too!

Make SURE they are warped before replacing, as bad rear rotors are both more likely and will cause the exact same "warped rotor" feel.

I'd not bother to keep the old pads, as they could very well be the cause, although driving style may have more to do with it. You can re-use the sensors if the wires will coil back up.

In the future, avoid near panic stops from high speed coming to a complete stop and standing there with the brakes applied -- the heat will not dissipate from the area under the pads, and pad material will then stick to the rotor, causing it to wear less than were there is no pad material.

Leaving them too thin will make this much worse, that's why I suggest looking at the rear brakes -- they get neglected much more than the fronts.
