I made some notes on adding antifreeze after my latest winterizing session and would greatly appreciate comments. Please send along your additions, deletions and corrections. The notes are in a PDF - MS Word outlines are not compatible here.
Thanks.

When you say "Nautilus pump", are you referring to the water pump button in the Nautilus compartment? On my Tab 400, this is a second water pump switch that can be used to turn the pump on or off if used outside. Same functionality as the interior water pump switch - no difference between them.
After I finish pumping antifreeze into all the faucets (hot and cold), I also briefly open and shut the low point drains in the Nautilus compartment (you might be covering this under "all outside valves" but I find I might overlook it if I don't call it out specifically), as well as the gray and black tank valves -- with outtake cover still in place. This allows antifreeze to coat the valves themselves. Finally, I pour a generous amount of antifreeze into each of the drains - kitchen sink, bathroom sink, shower drain and toilet, leaving a cup or so in the toilet itself. Two gallons is sufficient for the entire process. I also leave the interior faucets slightly open to relieve any pressure that might build up.
I love checklists - makes the process repeatable and reliable.

Some great comments.

I use the external water pump on a regular basis - that outdoor shower is very handy in rinsing off muddy hiking boots - and dogs!
