Surfnsnow,
Welcome to the forum

, more info on restrictions/limitations would help folks craft some useful suggestions:
1) Why are you leaning towards an in-ceiling solution vs either an in-wall or stand alone speakers? (WAF, asthetics, small children, etc.)
2) As stated earlier, a ball-park budget would really help.
3) Concerning music, is system going to be for critical listening (or build to this eventually) or just general background music (ambiance, parties, etc.)?
4) Concerning movies, is system going to be your primary home theater or an alternate/convienent place to watch a movie now and then?
5) What is the room like, dimensions (including ceiling height), openings to other rooms, and any other characteristic which may affect sound or video (e.g. cathedral ceiling, large window, hard surface floor, etc.)?
Look forward to hearing more about your project.
