My revision based on the new pix. Still like the idea of a round foyer table in the large hallway. The dining area definitely needs to be moved near the kitchen where the tufted chairs and doors are. I'd anchor it with a rug that is at least 4 feet wider and longer than the table. It appears the tufted chairs have a matching sofa. I'm revising my 4-chair suggestion for the FP now, and suggest the sofa facing it and the two chairs between the FP and sofa facing the dining space which is now out in front of the kitchen door. Anchor that seating with its own large rug. In the end where the draperies are I'd use the two sofas facing each placed perpendicular to the windows, each 18" from the coffee table. The chairs can go at either end of the coffee table, one near the windows and the other with its back to the open room to form a closed conversational grouping. Loosen the drapes and let them fall loosely. Once the arrangement is worked out, we can tackle painting, if you want.

I think your inclination toward rustic and distressed pieces is the right way to go. Consider a movable coffee table - I see 2 recliners that may necessitate some table shifting?- an area rug large enough to incorporate all the seating, rather than just a hearth rug, and enclosed storage for your electronics. If you can post shots of the room, other Houzers may have some more ideas.

How can we suggest lights, furniture, windows, etc. without pictures, floor plan blue prints, description of your style, color preferences, budget... this would be like decorating in the blind!

If you want to let in more natural light, I suggest either solar shades or sheer shades. Both let in plenty of natural light without sacrificing privacy. Here are examples of both: http://www.blindsgalore.com/solar-screens http://www.blindsgalore.com/sheer-shades
