Devious-
For some reason I wasn't notified of your post, I am getting real close to parting out....but for now I would still like to get rid of the whole thing in one shot.
No return pump. As to plumbing you would only need a short length of either 5/8 or 3/4 tubing (off the top of my head I can't remember which and depending on size, I may have a piece for you). to run from the return pump to the return bulkhead.
