Michael,
"going from one image capture setup (the camera) to the PC which has its' own color calibration"
That is exactly, why Photoshop (and any other serious image manipulation software) uses ICC device profiles. The profile tells the PC what the camera "means" when it says "R100 G50 B255" to describe a pixel. To have the same visible color on a screen, this could mean "R87 G53 B243" and the printer's profile translates it to "R96 G59 B253" for a certain paper.
Only with these translators (color profiles) a shoot can yield controllable output. (Just imagine a TV spot for IBM in warm orangy colors and soft gradation...)
Therefore "Auto Correction" in PS is a very limited option to compensate a missing profile.
