Living Room Layout Dilemma

I have been trying to figure out how to lay out our new living room for weeks, so maybe you wonderful readers can help me out.  The issue is the shape of the room and the difficulty of having dueling focal points.

The room has a working fireplace flanked by lovely built-in bookcases and storage.  The plan is to highlight the backs of the two sides of shelving by painting them an accent color.  We might also paint the brick, but that has yet to be decided.

The fireplace would make a splendid focal point on its own, if we were to leave the room as a formal living room.  I really want it to be a space that gets used though, and I know it won’t unless there is a TV in there.  Sad, but true.  (There is no way to run cords around or behind the fireplace, so mounting the TV above the mantel is right out.)

LIVING ROOM

The living room is long and narrow with a large bank of windows that provide the room’s only natural light.

So, how do I make this long space cozy AND accommodate two focal points? And, to sweeten the issue, how do we feel about putting an area rug ONTO wall to wall carpet?

Discuss.

So, what do you think?  Which of these layouts do you think would work best in The Mad House living room?  Vote in the poll below!

EDIT:  Oops!  Forgot to add Choice G to the poll.  Dur.  If that's your fave, vote for F but let me know in the comments.  Thanks!
