I prefer pfc pads over pagids. I have used both and the pfc's are far more consistent and last longer than the pagids which seem to crumble and lose performance once they are about 50% worn. I was running pfc 08 front 06 rear on my spec boxster.
Rotors, I recommend to go with a slotted rotor. Not drilled as others have said they will crack too easily. For slotted there are a few choices. To name a few: ATE Premium one, sebro, or contact Chris at LC Motorsports. He makes custom coated/slotted rotors for spec boxsters that are a little mroe expensive, but worth the extra money in my opinion.
