Speaker Shuffle

After my binge on EBay, and other acquisitions, I've got the following speakers:

NHT SuperOnes (2)
NHT SuperZeros (2)
Paradigm CC-350 (center channel)
Yamaha NS-777 (2)
Cerwin Vega D-7s (2)

(Also, I've got the Polk in-wall and in-ceiling speakers already installed)

Here's the deal: I need speakers for the living room, which is occasionally used for TV/Movies, but usually music. I need speakers for the HT. I have an extra pair of speakers right now.

I bought the NHTs several years ago; they're great speakers, but relatively inefficient, which means they take a lot of power to drive them. They really didn't fit into my open living area because they just didn't put out enough sound. I was given a pair of Cerwin Vega 'rock and roll' speakers, and just had them re-baffled (the foam around the subwoofer). They do pump out the volume, so Steff has decreed that they'll go in the main living area. I got the Yamahas from a friend, and they're beautiful speakers- big tall towers. I'm trying to figure out which speakers will be better for the HT- the NHTs or the Yamahas. It is a tough call. Of course, whichever ones don't go into the HT... where do they go?
