Unfortunately PS CS doesn't have that neat little tool that PSE has where you can just go in and click on a cast to remove it. Fortunately you can do a better job in PS CS with Curves.
1. Open the Photo with a color cast.
2. Image>Adjust>Curves
3. In the Curves dialog, click on options.
4. Set your Shadows to (RGB)20, 20, 20, Midtones(RGB) to 128, 128, 128, Highlights(RGB) to 240, 240, 240
5. Click on Save as Defaults, then OK
6. Using the Eyedroppers at the bottom of the Curves dialog, click on the Black(shadows) and then select an area of the photo that should be black. Click on the White one(highlights) and then in an area in the photo that should be white and then on the Grey eyedropper(midtones) and an area that should be middle grey.
If you are not sure which areas are correct for black and white, temporarily exit Curves, and in the Layers palate, create a new Threshold Adjustment Layer by clicking on the half white/half black circle and selecting Threshold. Move the slider all the way to the left and then to the right to identify the shadows, and vice versa for the highlights. You can use the color selection tool in the tool box to mark those areas if you want to. Then toss the Threshold layer. Reopen Curves and follow the above.
7. Select a midpoint on the Curve and move it verically upwards to lighten the midtones.
8. Click OK
9. You can adjust the overall effect by immediately going in to Edit>Fade Curves. When the dialog appears, use the Fade slider to adjust the intensity of the Curves adjustment.
