Staci, welcome to the forums. You'll find alot of information and a ton of helpful people here. I'm sure with a little more info we'll be able to help you.
I'm curious as to why you are looking at in-ceiling speakers versus wall mounted for your media room. I checked online and the Klipsch RC35 is listed as a Center Channel speaker. Are you using these are fronts as well?
I'm assuming for your media room will primarily be used for home theater, movie watching, gaming, correct? What kind of display are you running in there? are you going with a projector or flat screen display?
Your living room speakers will probably be using a different set of speakers depending on your intended uses, same for master bedroom and bath.
Some of the questions I ask folks before an install, what are you intending to use the room for? How many people will be using it with you? What is your budget? Are you going to be adding/ changing the room structurally? etc.
