I think it's all personal and relative here. I mean, everyone has different gear out there, everyone!..even the audiophile/reviewers for magazines have completely different setup's.
That all said, you could go a number of dirrections. You could do the 2 channel w/subwoofer and pre/pro setup, which many audiophiles do. This setup makes sense for 2 channels guys, or those who wish to keep things simple, but want to spend the bulk of their money on heigher end gear in a certain budget...which may be right up your alley!
All you'd need to do is keep it 2 channel (either full range or satalite fronts), add a MUST NEED subwoofer, AND a dedicated A/V pre-pro. This is a MUST for properly processing DD/DTS! You can't get the same results by simply processing in the DVD player or source, and going straight to your 2 channel preamp. This is never as good.
The next audio alternative is of course to invest in some high quality satalites that will do justice to movies and music both, IN YOUR ROOM/SETUP! The speaker selection is key/paramount here for best results, far more than the gear!
If your setup is such that you can sit closer to the speakers in relation to the ceiling and sidewalls, or you have very good acoustics and treatment in the room, then you can get away with higher end traditional music monitors(i.e., tweeter over mid/bass drivers) IF NEED BE. But I'd still like to see multiple driver arrays or horns and or more active designs to maximize the focus, dynamics, solidity of image, impact, speed, and pressence that you NEED for a properly potent home theater system! Most people fall short here, and don't know what they're doing.
If you sit back further from your setup, have low ceilings accordingly, and or have to have your speakers near the sidewalls to boot, you must consider the above mentioned Dappolito, THX, Horn loaded, or other more "controlled focused" designs. Otherwise, you need major acoustics in place to negate first order reflections from destroying your sound!...and they will do just that. You can thus look foreward to a soft, un-involving, smeared, dynamically wispy, faint, and generally confused sound if you don't take care here. (20 years and 6 high end audio stores worth of experience talking here).
All that considered, you have to ask yourself what you're room/setup would involve before you can properly adress your speaker choices in my experience...this is critical.
Your choices also depend on HOW BIG YOUR ROOM IS!
Narrow down your room considerations, and I'd recommend "no lose" choices for your needs, sure.
