Pretty much! Here's my procedure.
Drain fresh tank, open faucets, relieve all pressure from the system.
Go to WH, open the safety valve, which makes sure it still opens, check for pressure. Then remove anode rod and walk away.
Since I now have low point drains, this is where I'd open them.
Use compressed air a few shots worth. That will push water out of the lines supplying the WH. Then, bypass the WH using the valves.
Use more air pressure to push remaining water through the faucets (Again, since I have drains this could possibly be omitted.) and make sure they're clear.
Use water pump to pump antifreeze through the system. Just let it run until solid pink throughout each faucet, shower, toilet, outdoor tap.
Come spring, put about 15 gallons of plain water into the fresh tank, push antifreeze through until clear throughout, open the WH bypass and let some water flow through the WH to rinse anything out the anode hole. Reinstall anode.
To sanitize, drain fresh tank, then pour in a water/bleach solution. I'll let you look that up as my method got some interesting comments.
Run water/bleach solution through until you can smell it through every tap, hot and cold. Let sit, again opinions vary.
Drain anything left in the fresh tank, refill with fresh water or just hook the hose to the city port, rinse water/bleach solution through. Done.
It might look like a lot, but once you do it a time or two it doesn't take long at all.
