"iCloud music library session expired" and auto-sync - Can you make it stop? I can't.
TL;DR version: Please, please, please, can anyone tell me how to make iTunes (on Windows) stop saying: "Your iCloud Music Library session has expired" and asking for my password? And can you please tell me how to make it stop auto-syncing with my iPad every time I plug it in? I will be forever in your debt if you can make it stop.

I tried asking in iTunes for Windows but got no reply, so I thought I'd try here. Also I was kind of ranting before (iTunes has a unique ability to fill me with such a rage that the Hulk would run in fear) so this time I'd like to calmly ask for help haha.
Basically, I have two problems with iTunes and I'm not sure if it's just from upgrading to 12, or if it happened when my iPad was broken and I had to reset it a couple times. My iPad is fine now, the problem is somewhere in iTunes.
Every time I open iTunes, a window pops up saying "Your iCloud Music Library session has expired" and it asks me for my password, twice in a row.
Every time I plug in my iPad, it starts to automatically sync and I have to stop it. Because of this I'm too scared to try plugging in my iPod Touch which I keep my music on.
I want both of these things to stop and for the life of me I can't figure out how. I don't, and have never, used iCloud, Match, Genius, Syncing, whatever this new "Apple Music" program is, or anything that takes away my direct and total control over my content, so I have NO idea why this keeps happening. I haven't even bought anything directly from the Store since Avenged Sevenfold's "Nightmare" came out. Every setting I can find on iTunes and my devices that relates to iCloud or Syncing is disabled, as it always has been, and I've even disabled a few more things to be safe. Maybe I missed something but I don't think so.
---Sorry, this is where I get long-winded, but I'm just explaining how it started in case that leads to it stopping:
This never happened until a couple weeks ago. My iPad had problems so I took it to the Apple Store and they fixed it with a factory reset. While we were running through the setup, I was just trying to get it done so maybe I enabled iCloud on the device by mistake. I came home to restore it through my iTunes backup, it asked me to "trust this computer" and all of that. And THAT'S when iTunes started asking me for an iCloud password. That's when it started trying to sync. When I tried to do the restore I did something dumb that led to a second trip to the Genius Bar and a second factory reset. I took it slow and paid extra attention this time. Said no to iCloud. Yet I got home and iTunes still wants a password and it still wants to sync. I only upgraded to iTunes 12 a few days before my first Store visit, so that's why I'm not sure which event caused the problem. (I heard bad things about 12 but man I wasn't expecting this.)
Solutions?:
1: The first few times it asked for my password, I didn't realize what it wanted so I just did it. But it asked every time I opened it again, so the problem can't be fixed by just logging in like it wants me to. Can it? Is there something that I just need to log into or out of, to make it shut up and stop syncing but not allow it to change anything?
2: I've considered uninstalling iTunes and reinstalling to see if that fixes it, but I feel like it won't so I don't want to risk it unless someone can tell me it will work. I'll do it if it'll help.
3: If this is just the way iTunes 12 is 'supposed to work', then is it possible to safely install an older version of iTunes from an official or reliable source?
4: I know I had an online chat with an actual, real live Apple person last year who kindly answered my questions even though my computer was being the slowest thing on earth that week. I've tried to find that real-person link again but I can't. I'd rather not call but I'm so desperate I even tried that. I got a robot. So I'd prefer chat if you can still talk with Apple humans at all. Email works too but, surprise, can't find a link for that either.
Really, I'll take any and all suggestions for a solution. I'm not computer-illiterate or anything; I'm no expert but I can work through most problems. But I've always had the WORST luck with iTunes, it's literally made me cry more times than I'd like to admit, and I just really, really want it to stop doing this. You have no idea what it will mean to me if you can help.
Sorry if this was too rant-y. I wanted to keep it brief but it's hard for me to be calm with iTunes. And I wanted to include any relevant information that might resolve this. I'm using the family computer now; I'll be buying/building one of my own in the next few months and I do not want to have to deal with this when I put iTunes on it. (I never bothered to put iTunes on my laptop because of things like this. I'll have to put it on my desktop though.)
