this article might help, although it is a little out of date as in it doesn't mention some of the newer pads out there like the
sonus pads.

but other than that, it's pretty informative in describing the differences between porter cables 7336 and 7424 etc.
also check out some of the major vendors listed under the "Detailing & Car Care Supplies" Web link, like the autopia store, autogeek, or classis motoring accessories. these vendors should have a pad starter kit which includes a bunch of different pads (at least one cutting, polishing, and finishing pads) along with the correct backing plate.
good luck and happy detailing!
