I've had slotted/crossdrilled rotors on cars before, and honestly, for a daily driver.. all they do is chew up pads faster. Stick with high quality blanks. I've used Hawk HPS pads in the past and never been disappointed by them.
Oh, and regardless of what you choose, make sure you bed-in your new pads properly for best performance. Hawk recommends 6-10 moderate stops from 35mph, then 2-3 hard stops from 45mph, then park and let them cool off completely.
