[/quote]From looking at this photo I would place my tv in the wall where the sofa is now.
Then I would place the sofa in front of that window, I would use spacers (at the sofa feet) to keep the sofa off the wall about 2 or 3 inches
Coffee table in same spot, and I would purchase 2 nice occational chairs to place where the love seat is.
Use an area rug to pull everything together
Something like the photo below but the TV would be where the patio doors are
If you don't like the two chair idea, I think a skinny chaise would look a nice. The no back might give an open up feeling into the next room
