Floorstanders that have a strong bass presence might be a little too much for a smaller room, especially if they're rear ported, and I wouldn't normally recommend using the supplied bungs to fully bung them up. I use KEF R300's all round, which aren't exactly bass light, although the Audyssey I use is more advanced than the one in your 7005. I use a partial bung.
For AV, you can use floorstanders or standmounts, but the main consideration will be for music. many people prefer foorstanders for music as they don't want to use their sub for music. Even though I know the R500's would've been better for music in my system, I just couldn't fit their height in.
If you wanted to go B&W, I'd say you'd have to look at the CM8's to work well in a small room rather than 600 series, although you might get away with the 684 if you used them carefully. I think the MA's will be too bassy for your room, so you'd have to look at the RX1's (RX2's might be a little much too). The tannoy Revolutions should be ok, as would the KEF Q500's. Again, I think the Q700 will be too much.
Obviously smaller sub/sat type system like Monitor Audio's Radius and Apex will be a safer bet, but they'll not quite match up to the musical quality of some of the speakers already mentioned.
Alternatively, you could make up a 'sub/sat style' hi-fi speaker package. You could try the KEF R100's all round, the Monitor Audio RX1's all round, or the B&W CM1's all round, so you'll have the convenience of a sub/sat package with the musical quality of a hi-fi speaker.
With careful use of the AV receiver's EQ, you can bring bring more presence into the room at lower volumes if you find things a little too smooth. personally, I like my system to have a bit of bite rather than sounding like each speaker has a blanket draped over them.
Only use the Bristol Show as a guide, not a decision maker or breaker. Those hotel rooms don't sound like your average living room...
