1. Besides your home theater, in what other room(s) in your home do you want great sound?
Ideally, all of them, but, short-term, the living room and the master bedroom.
2. Would the audio in the secondary room(s) come from another room?
Good question. Probably not. Don't want to invest in the controls needed to do that.
3. What type of speaker system would be in the secondary room(s)?
Nice pair of bookshelf speakers, ideally.
