Help! As you can see from my old tube TV, I'm in dire needs of a tech refresh!
I might be the last holdout to purchase a flat screen TV, but the time has finally come to join the 21st century. 
The house I bought last year is an open floor plan and was not designed for AV. The cable drop was coming out of the floor in the middle of the room! I'm having trouble making decisions with all the constraints. I'd like to avoid the popular over-the-fireplace location, but I don't know how this will work given my furniture and upright wall piano (not shown in photo above).
The room is approx 16'x15'. It gets lots of south-facing sunlight and you can see I've already invested in some insulated curtains to block light and heat. Budget is about $4k for TV, receiver, and speakers. After this project is done I'm building a deck outside and want to run a second stereo zone from the same receiver.
I just taught myself some basic Sketchup to model pre-construction ideas for SWMBO. See below for some mockups. She's not diggin' putting up walls and breaking the open floor plan model, so I need some good backup material if that's the best option!! I'm a moderate DIY'er.
Layout options that I see:
1) Build a 4.5' half wall to mount the TV.
2) Over-the-fireplace installation.
3) Use an angled entertainment center in TV's current location, possibly a built-in.
4) Are there more options??
The surround sound setup is of course driving decisions... I'm dumbfounded. Also, I have no idea where to put my electronics gear.

Excited to hear any suggestions!! Ready to purchase elex now!
(TV modeled below is a Panasonic 55" GT50.)
Thanks,
