Hi, Dennis
I will tell what my workflow is and you can see if it may help you in some way.
I shoot in raw and ingest the raw files with PM into my MacBook.
Then I review the photos in PM, color sorting, tagging, and deleting the really bad pictures. After this first round, I rename and apply basic IPTC to the remaining pictures (still all raw).
After that, I open the pictures in DPP (LR, in your case).
In DPP I correct exposure and white balance, and crop the pictures, if necessary. After all that, I use DPP to convert the files to JPEG maximum resolution, maintaining the same names.
Finally, I open the files in PM (raw and jpeg together) and review the photos again, checking if there are any other photos to be deleted and applying IPTC data to specific photos, like keywords and captions.
After this last round, I rename the photos again with PM.
