Welcome Rusty!
Winterizing an Intex is pretty simple. The pool should have come with some black plugs, those go in the holes for the tubing on the inside. You could lower the water level if you want, but it's not necessary unless you have a through wall skimmer. Then you can disconnect the pump and filter, drain and store them somewhere dry. Get a couple ring pool floats, stack them up and then put a beach ball in the center. Tie them so they don't come apart and then put those in the center of the pool under the cover that came with the pool so it's like a tent. I'd suggest then using a tarp over the cover and weigh that down around the pool with some bleach jugs filled with water, or you could get some tent stakes and stake it to the ground.
It will get some water collecting on the cover around the edges if it's not tight, but it shouldn't be a problem. Just go empty it when you can. Snow shouldn't be a problem, as long as the water is in the pool it won't be an issue on the frame.
Insofar as water chemistry, can you tell us how you're chloriniating and testing right now?
