My workflow:
1) Import RAW files directly into LR from card reader - location is: Photo Library/Images/2013 and then a subfolder with 4 digit number for month & day then a brief description (like 0101 -John & Mary Wedding). This path can be set up on any drive. I use a drive other than the C:\ drive
2) Process the photo in LR to my liking
3) Right click and select "Import". In the Import Dialog I create a subfolder under 0101 and name it PSD. I select that the photo is to be opened as a PSD file and be opened in PS6. Make sure that you save it to the newly created location in subfolder PSD (If you are doing a lot of photos in the 0101 folder you can save this as a preset. Give it a name like PSD John & Mary......or whatever you like)
4) this opens the file in PS6 and there I complete my adjustments, make sure it will be saved in the new PSD subfolder, select to delete it and then select to save it.
5) back in LR find the PSD file and right click on it and select "Import" again. Now create another subfolder under 0101 and name it JPEG. Select it to be saved in .jpg format, select the size you want (use the same number for both horizontal and vertical, like 1024 x 1024 or 1280 x 1280 and select "do nothing" under "Post-Processing". Again, make sure the destination is set to the new JPEG folder and again create this as a pre-set if you have a lot of photos to do in 0101. This makes a .jpg image suitable for email and preview etc.
If you really want to set this up, there are some details left out here and I'd be glad to help you with the whole process if you have questions.
This is something I created that gives me the images I want to have available for use any time. There are nearly an infinite number of ways to accomplish the same thing. If anyone reads this and has better ideas I'd love to hear them.
