Yes, you should be able to replace the window motor and regulator yourself at this point- easier if you purchase it as one assembly motor and regulator together:
I understand with the door panel completly removed. How do I remove the lock mechanism and switch wiring for the locks and window? I should be OK but I am working on the drivers side window
You shouldnt need to remove those. Once you have the window disengaged from the regulator and have regulator unbolted, you will pull the assembly out and installing the new one does require some wiggling to get it in place.
