For a PDI, go to the Tech Topics section and open the first sticky, Ed Felker's Vegas/Axis Manual". It has a great PDI that you can print off.
Your DMV can tell you how to handle the licensing. The DMV might give you a temporary paper plate to use in transit. We bought our Vegas in Ohio and took it on a trip before returning to Iowa.
In Florida we keep our plates. We moved our plate from the old coach to the new, and were back before the deadline to get the license and registration. If you have a bill of sale with you, you should have no problems on your way home.
You should easily find a bill of sale on the web. I have bought and sold many vehicles with simple homemade bill of sale sheets.
Good luck with your negotiations!
I think we need to stop calling it "working from home" and start calling it "living at work!"
