Probably the lowest dusting brake pads commonly available at the moment are the Raybestos Quiet Stops. These are the ceramic based pads. NAPA and Car Quest also sell the same pads with their own label on them. From what I have read, they do not stop quite as well as semi metalic pads, but for most drivers the difference seems to be more theoretical than actual.
Personally, I don't think much of either slotted or drilled rotors. Don't do it to imporve braking, they really don't. They cause other problems though as the holes or slots are stress risers that are the originating points for cracking. They also make it more difficult to machine when the time comes. If you feel that you must have them for looks, just be aware of their limitations.
You may want to check out the rotors (pads too if you are looking for semi metalic) at BAT.

Neither Mintex or EBC pads are particularly low dust, but each has their loyal following for their performance.
