Focus on two-channel first and foremost. Once satisfied, add a subwoofer and tv (Plasma, or front projection would be best to keep things clean). If your pre has two sets of main outs then one set can go to the sub and the other to the amp.
I believe that if you get the 2-channel right, then you'll enjoy your movies almost as much.
