Check the swatch thread on here. There is a thread entirely dedicated to MAC pigments. There's also another pigment thread around here that shows custom mixes of pigments. KarlaSugar's blog, I believe, also has a bunch of pigment swatches, and may include some Pro ones.
As for pro shadows, you'll have to do a search in the main swatch request thread. If there's a particular shadow you're looking for a swatch of, but can't find, then you can request a swatch of it in that thread.
HTH!
