need help for family room (layout and furniture selection)

[hheaven]

I need some help for my family room. It's for 2 (my husband and I) so I don't need much furniture but still want to fill out the room.

One of the piece that I want is H&M Monaco sofa but I still need other pieces.
I also thinking to buy campaign cocktail ottoman instead of coffee table. Although, I am not sure if this will be too small or not for my room. I was hoping to get feedback and help on this one.
My husband seem to doesn't like the Plantation Ottoman. If the Cocktail ottoman is too small, I may go with the Campaign bench.

The family room layout is slightly weird. There are 3 big windows on west facing wall. The fireplace is at 45 degree angle on the left portion of the wall and there is sectional for the TV on the right portion. Because of this with I thought about avoiding furniture on westside of the room (near window and fireplace).
Although the built-in sectional has a place for a TV, I may not put a TV in the room. There is a separate media room upstairs and I may only put the TV upstairs.

I tried to draw layouts with different furniture. The masking tape on floor is for the Monaco sofa, and a chair and half or a loveseat.
I prefer to place a sofa and chair&1/2, but I'm not sure there is matching pieces for chair&1/2 with Monaco design. The chair & 1/2 only seemed to available in the City and the Austin design but I wasn't sure if it will work well with the Monaco. I was hoping to get feedback and comments on this as well.
