You might also check out DxO Optics Pro. I use it to batch process almost all of my shots before I add them to Aperture.

It supports a large numbers of cameras and lenses and corrects optics and geometry problems of specific cam/lens combos, among other things. It's a powerful app, but I have honestly only scratched the surface of its features.
