Let's see.. the #9 might not be aggressive enough for your marring, even with the yellow (cutting) pad. And generally, whenever you use a yellow pad, you oughta follow up with a white (polishing) one. So I'd at least plan on a second pass with the #9 using a polishing pad.
Most people would do the S100 by hand instead of using the PC/gray pad, but I do paste waxes by PC all the time.
