yes I know how you feel a couple winters ago I was working 80-90 hours a week and the only tv I got to watch was the pc monitor in my office which was 20"s, and when ever I made it home I always spent time with the family so no tv, then when it slowed down and I finally got home, watching my tv took some getting used to, it seemed like a movie theater and was only 46"s LOL...
That sounds like a really nice system, simple and quality, what more could you ask for... If you are still undecided on placement when you get in there let the sun dictate the position of your tv, I set my bedroom all up with the tv on the largest wall, until we moved in and tried turning the tv on during the day, you couldn't see anything, even after shutting the blinds it was almost impossible to see when the sun was out... So we moved it since we went out of our way to get extra sun in the bedroom when building the house, my wife didnt want to buy black out blinds... its something to think about...
