This is my first winter with our pool and I keep getting worried that I'm doing something wrong that will damage the pool come spring. Last night, I actually dreamt that the pool sides collapsed! Here's a picture of what I have going right now (apologies, picture taken from upstairs through window):

Pool level is about 6" under the skimmer, etc. I've got the winter cover on the pool with milk jugs tied around to keep it from blowing off (the wind blew it up a few times already this fall). I also have two winter pillows inside the pool under the cover, but they've floated to the sides... is this an issue? I've been draining the water off the pool with a hose periodically, but I'm wondering if I need to keep doing this or if I can just let it go. Now, a light layer of ice has formed over the water. I also haven't covered any of our equipment (pump, filter, heater)... should I do this? What's the best way to cover it? Just secure a tarp around it?
Oh, and I live in Cleveland, Ohio, so we get pretty tough winters. Lots of cold and snow. I'm wondering what's the best way to prepare the pool for the snow (since once it starts falling there's not much I can do to help it).
Any advice is appreciated.
