You mentioned "theater", so I assume straight movies is your priority, correct? If this is the case, and you're only using a receiver to drive speakers (although that receiver has nice sonics, albeit not tremendous power), then you would do very well to consider "horn loaded" speaker like Klipsch, or "powered/active" type speakers with at least powered built in woofers! the receivers sound rather week compared to even modest separates, and need all the dynamic assistance they can get! High sensitivity horns and speakers with powered/active drivers help receivers sound much much stronger and dynamic!
If you want to do a really potent HT with that receiver, I think, for really cheap comparatively, you could do something like Klipsch RB3's up front, and possibly in the rear(set up well of course..which is key to good sound always), and cross em over to "small" and let a good powered sub or two handle the bottome end! With the clean sonics of that receiver, coupled with the very dynamic sound from the Klipsch monitors, you'd be blown away at the excitement level and sound quality of this midfi system! I would bet you anyone who heard it, if you set it up right(and I've set up over 1000 systems), would be blown away by the pressence and quality you'd get from the sound for either movies or music! Yeah sure you can get some more musically refined sounding speakers, but not better for your applications really...and it would still sound plenty good for music!...trust me.
good luck...
