I'm not sure why you're using RSE to sort them, and then process the RAW in Photoshop. RSE is a RAW converter and that is its primary purpose.
But in general with CS2 the workflow becomes quite straight forward.
1. Load images to folder on HD.
2. Load Bridge. Select a group of images that were shot in a similar lighting set.
3. Enter the PS CS2 Raw converter. The selected images will be on the side as thumbnails.
4. Do a conversion of a representative image.
5. Select all and do a syncronize. Now all the images have been set up to convert with the same RAW settings you applied to the image in #4
6. Do any cropping and straightening.
7. Open the group in PS CS2 for final post processing.
8. Save processed photos to whereever you want.
The RAW images will all stay in their original location. There is no need to move them around.
I usually delete some photos at the very beginning of the process. Any that are totally messed up go at that point. During step #6 above I use the mark for deletion icon in the CS2 converter for any that I don't want to keep. So I'm doing two stages of deletion.
The images in this example (model Holley) were all done using this workflow. This grouping took about 90 seconds to process using that workflow.
