My favorite street pads are actually Porterfield R4S's. They stop well in all weather/temperatures, have a reasonable amount of dust (not dust less, but less than OEM - dust is actually a lighter color gray than most brake dust, so your wheels appear cleaner), and don't squeal much at all. I've tried everything from Performance Friction (love their -01's and -06's on the track), Hawk, Akebono, Porterfield, and OEM over the years. There is always a tradeoff, but the R4s's hit the sweet spot for me.
Also - my experience with slotted rotors is that they increase both brake dust and pad wear.
