You don't mention a budget but for $500 I'd look at an Oppo BDP-93. For $300 I'd look at a Sony PS3, yes it's a game console but it's still a great Blu-Ray player. Under $200 I just don't know but Sony and LG both have excellent players at that price range.
It's impossible to suggest a sub without knowing how much cubic footage the sub(s) will have to deal with. I'd take some measurements of the listing room and any spaces open to that room including hall ways. Include the ceiling heights so you can calculate cubic footage. Sketches are helpful to. Once you have all that information contact SvSounds, Hsu Research, and Rythmik and have them each size a solution for your room.
