Open multiple images in CS2. Do to them as you see fit - cloning, levels whatever. Then run your action. If you've coded your action correctly you can have it save and close the file, then move to the next open image.
I use a folder called "end result" that all my processing dumps into. From there I move it to its permanent place.
Tandem, feel free to pm me and I can give you some in depth pointers on how to automate your actions. CS2 and it's actions pane are a pain and to me are the place where Adobe could clean up some code and add some features. I also have some actions for sharpening you may want to try.
Bottom line is I can open multiple raw images in ACR, adjust as I like. then they fully open in CS2 and I press a pre-programmed button and all my processing is done automatically and saved to a folder with zero input from me.
As corey mentioned, if you are knee deep in Lightroom for RAW processing you can still take advantage of this by using a droplet.
