Going From 1978 to 2018 In One Fell Swoop

I have skimmed many of the "What should I buy" answers in this forum, but still don't have a clear picture of what I need. But I do know what I'd like to accomplish.

Basically, my wife hated the Advent Legacy II's we bought in 1991 and talked me into Paradigm bookshelf speakers in '06. Now she hates seeing speaker wire string along the floorboard everywhere... So I suspect a Sonos system, of some type, is what I need.

Here is what I would like:

* Stereo speakers in the living room
* Stereo speakers in the family room (two floors away)
* A speaker (I'm OK with mono) in the master bath
* A speaker (again, mono is OK) on the roof deck

1) I would like to have them all access my component system - an amplifier, Eq, CD player, and turntable.
2) I believe that, by virtue of being Sonos, they'd each be able to access my Sirius and Pandora accounts.
3) I would love to have them access my iTunes library. I am willing to let it sit on a dedicated PC (the entire library isn't on any individual handheld device - OK, I have an Android phone).

I presume the living room and family room speakers should be -3s or -5s, yes? And I'm probably OK with a -1 in the master bath. What could go on a roof deck? (Are there any rechargeable options - so I don't have to run power up to the roof?)

I know the 5s can handle a line in, but if I do that - that means ONLY that 5 can play the components, right? So do I need to connect the component to a CONNECT? And then that will route to whatever rooms are necessary?

I know I can't control the CD changer (or flip a record) with the Sonos app, but I can route a component system to multiple rooms and adjust the volume with the app on a device, correct?

OK, let's talk iTunes. Like I said, I'm happy to put my 120GB library on a PC and push from that to the system. Is there a way to control iTunes with an app? So the interface sits on a device, even though the music files are on a server? I guess it doesn't *have* to be iTunes - just something that will play AAC files (and ideally import Playlists).

My only experience with Sonos was in a streaming-only household. They had a speaker in the upstairs teevee room and one down in the living room. Everything was controlled with an app - but it was only the services that they subscribed to (Sirius, Pandora, Amazon Music).

Thanks in advance. Let me warn you in advance - I'm a cranky old man who doesn't do well with vague technospeak! Answer with acronyms and abbreviations, and you can kiss your frisbee goodbye...

Thanks!
