Angelo,
You have PM.
As far as your questions, a "nude" pair of Orcas is just divine with acoustic jazz, and no worries with a 45 in your size room with such music. Don't expect to do Mahler or Bruckner though. Also, don't write off the sub as this is not a typical sub -- no boom, no room loading issues, easy to get seamless integration by simply adjusting the level, crossoverr point and moving the sub around a bit and it can easily be set to just fill in the bottom notes.
Everything is beautiful with a setup like this -- soundstage, ambient recording venue recovery, tone, etc. Drum kits, pianos, acoustic bass all sound wonderful, and the best tenor sax I've ever heard -- as long as you don't push them beyond their limits.
