Hi Anna,
You seem to have it knocked. Lot easier winterizing an AG pool compared to an IG. Can't comment on the polyquat since I don't use it and the only thing you didn't mention is draining the pump. Probably just an oversight in the post. Something you may want to do for curiosity since you're not covering, sink a 5 gallon pail to make a hole in the ice so you can measure the ice thickness. I use a couple Home Depot pails and found a smaller bucket that fits inside. I fill the smaller one with crushed stone for weight so the 5 gal pail sinks to within a couple inches of the lip. I then put a piece of plywood or something over the 5 gal pail to keep the rain and snow out. To remove, take off the plywood, remove the inner weight pail, then pull out the 5 gal pail and you have a fishin hole. If the 5 gal sticks just pour a couple quarts of hot water in it and wait a few minutes and it will come out. I'll dig up some pics that were on the old forum BC (Before Crash) and post them. Watermom tells me I live in the North Pole so I guess you must be at Latitude 89N since you're just South of me.

Here are the pics.
