My workflow is similar to duh59's workflow. The only important difference that I would like to mention is that I use Photo Mechanic to "injest" the images from the memory card, and then I rate them and pick the ones I'd like to edit in NX. Photo Mechanic works at lightning speed and works very well in combination with NX. Years ago Jason Odell had a video that showed how to use the two applications together for your workflow.
I also rarely use Elements after my post processing in NX.
