I've been reading all the posts and is seems like there are various ways to blow your pool lines. I think I'm targeting blowing lines from the pump housing back towards the main drain and skimmer. And then blowing through the pump (direction of water flow) and equipment to get the returns. I have attached pictures below.
Setup:
18K Saltwater Gunite
Pentair VS pump
Multiport valve
DE Filter
Heater
SWG.
Location: NH, much ice and snow
1 Skimmer, 4 returns. Cyclone blower
Procedure:
1. Backwash filter
2. Lower pool water 18 inches below returns. Will use main drain for this
3. Pull drain plug on pump, filter and (heater?)
4. Close main drain leg and blow out skimmer from pump. Water should come out of skimmer
5. Close skimmer, open main drain. Blow out main drain and airlock
6. Set multiport to Recirc
7. Blow out return lines from pump
8. Insert Return Plugs
9. Insert pool skimmer plug.
10. place drain plugs, filter pressure gauge in pump housing
Questions:
1. Is it OK to blow air through the heater and SWG?
2. I need to find someway to connect the blower to the pipes in the pump housing. I have some old vaccumm hose to make a short hose from, but I need a hose end to fit into the pipes. Im thinking some type of conical hose adapter to create a snig fit.
3. Antifreeze? I'm not sure if the closing company in the past used this.
4. Which exact chemicals/kits to use for closing. I think I will tackle that after getting the mechanical closing done.

I would add to your list above after you blow out the returns to set the MPV to either CLOSED or propped up in between two settings. Yes, pull all plugs and leave them out unless you are concerned about rodents trying to get into a piece of equipment. Moving air through the heater and SWG should be no problem. Antifreeze (pool or RV) is a personal option. Not everyone uses it. In your area, once the water temps crash and remain well below 60, algae shouldn't be an issue, especially if you increase the FC level close to SLAM level before shutting it down, but certainly up to you.
