Keep in mind the prices you list are regular pricing, you can save 10% from the factory outlet. In regards to prioritizing, that would be diffierent depending on who you talk to... everyone has different tastes.
Normally for surround sound purposes, you want to be "surrounded" or "enveloped" in the sound. The Q series speakers will be the best at that, however, some like to listen to a lot of 7 channel music or SACD's and DVD-A's. For these, some find a direct radiating speaker does better. I think the Q's do a great job for music as well, and I primarily use my setup for movie watching, so the Q's was the only way to go...your mileage may vary..
