I've been going through the same process as newbie after a 15 year hiatus and my best advice is to listen, listen, listen. Pick a few favorite CDs, a variety of music, and listen to as many amps and speakers as possible. They are all so different and the synergy complicates the listening.
If you like B&Ws then you probably like crisp sounding equipment so solid state is your best bet. The Arcam might complement this crisp, bright sound well as it is a bit analytical (I prefer warm sounding equipment).
I had similar room problems as you -- big room, wood floors, plus the spouse (she's not a problem, she just has opinions). I decided that I could not dedicate the room to a nice system with a correct listening location so after going through several iterations of equipment combinations I think I'm going to settle for a Linn Klassik and also get a nice small system for my office where I can really define things (I work at home).
But have fun too. There is lots of good stuff out there. Ask around, shop around, but only buy what sounds good for you within your budget.
But! Do your research, pick some items, and go listen! Your ears are your best guide.
