How do I go about transfering my actions and scripts from my "old" CS to my new CS2?

It should be as simple as finding the source files in your CS folder and copying them over to the appropriate folders for CS2. You may need to restart your computer in order for PS to see them, but perhaps not.

Added:

- For scripts, go to "Photoshop>Presets>Scripts"
- For actions, go to "Photoshop>Presets>Photoshop Actions"

I hope that helps!

Peter,
Thanks for the info! I actually learned that there is a "Save Actions" option in the actions menu that allows me to name and save all of my created actions in a desired location. Then you simply open up the new version, go to the actions menu, and click on "load actions" and bring in the ATN file that you just created... and BAM! you have your actions!!!
