Where does this wiring go? Does it all terminate in one central location, in the living room, or at plates in each room?
New wiring (planing to hire installers):
This is where i need help. Do, I plan for 2 channels in each room, regardless of size?
What do people typically do for a guest bedroom with attached bath? 2 speakers in each? or split R & L between the 2 spaces?
2 channels for each room. You can connect rooms together (share a zone between bed/bath) if it makes sense, but if you're running new wires, home run everything - you can tie them together at the head-end, but can change your mind later.
If the room is VERY small, or a hallway, you can use dual-voice-coil stereo speakers, but I'd avoid those generally.
I haven't decided if I need in-ceiling or on-wall since the latter would be easy to carry it with us if we decide to move.
If i do go with on-wall, would it make sense for buying a/v Banana Binding Post Wall Plate for 1 Speaker - Coupler Type from Monoprice or s'thing?
In-ceiling gives a much cleaner-looking install. Also tends to be better placement for background music (even distribution of sound throughout the room). If you go with on-walls, yes, a binding-post plate would the right answer. Honestly I wouldn't worry about taking these speakers with you when you move (unless that's in your immediate future). Five years from now, are you going to have a place for them, will they be still what you want? IMO better to do a more aesthetic install and make it a feature for future buyers...
Are there more of these go-dos, buy-these that I need to account for before getting the installers?
My plan was to buy all equipment and have them install. Or should I look for a more professional installer? (just fear the large bills).
Depends on the equipment. Retrofit wiring is an art, you want good guys doing the work to minimize damage. What kind of system are you expecting to use? Do some searches here for "whole house audio", and take a look at the HTD.com and NuVo products.
I did consider dumping all this & go for Sonos. Will save me from running wires, but I don't like their speakers (Play 5 sounds good but too big, Play 3 doesn't sound too IMHO).The way I understand, if I buy my own powered speakers, each would still need a Zp-90?
Powered speakers? If you want to go the Sonos route, you can use the Connect:Amp and just run wires in the room to whatever speakers you want. This saves the cost of home-running speaker wire back to a centralized amp. There is also the NuVo Renovia system that uses powerline networking that serves the same basic purpose.
