Wow, David, that was strange...
I was checking my email and you had posted the same question on the Yahoo Boxster group and I responded.
Anyway, no, they are not painted.
Welcome to the forum !

Edit :
Oops, my bad ! I just went outside and checked. The parts on the side of the oddments tray are indeed painted. I was thinking of the parts on the center console below the shifter.
Sorry
