My Family Room

My main goal for the next couple months is to transform my family into a room that is modern, stylish and comfortable. The room is still the beige color it was when the home was built 12 years ago. I still don't have window treatments and the fireplace is dated. Also, the room is long and I'm not sure how to layout the furniture and tv. Since I really don't know where to start and my funds are very limited, I decided to first paint my cabinet black. The color is "Blackjack" by Benjamin Moore.

The picture is bad because I lost the light in the evening.
