recommendation

The rear pads are due for replacement in my truck, wondering what your recommendations are for replacement pads? Also, should I replace the rotors while I am at it; currently has plenty of life left.

I'm currently running an aggressive 35" M/T tire, but my time on-road is increasing and the M/T is getting annoying. I'd like to step down to a 33" A/T tire to try and recoup a little fuel economy, but mostly for ride comfort (i.e. not vibrating on the highway) and lower noise. What do you run...
