Can you sketch out a floor plan with some measurements? The photos help, but the distances seem to be distorted, for example the distance from the corner of the fireplace to the kitchen pass-through in the 1st and 2nd picture.

Sarah, That layout was just a starting point for your room. There is lots of room to entertain different concepts for your room. Here's another possible layout for you to consider. This one has two sofas with 'cuddle' sections at each end facing the TV. I added an upright piano to the plan. Is this something you own or are you considering a baby grand for the room? Not sure this is the right room for a standard wall bookcase to store books. I'm sure you have an office in this house that might be scaled better to receive a standard 84" tall bookcase. Instead, you might want to consider sectionals that have matching bookcases that border the sectional like this example below. The bookcases act as book storage, display space, and console tables all at the same time. That long wall for the TV is 14ft. This photo below illustrates a cleaver use of a long wall that incorporates a TV and some display shelving if that is what you meant by bookcases for the room. Here are a variety of long walls with large TVs mounted on the walls and ways to address all the wall space that comes with this. I'd suggest you start with a rug that at a minimum is 10x14. It can be larger, as you have the room. Rugs this size can be pricey and limited in designs. Also, it's like hauling 2 dead bodies to move them so you'll not want to do that more than once. The plan also shows a long credenza or sideboard with art mounted above on the wall behind the two sectionals. This might be a great spot for placing a food spread if you entertain. Just keep in mind how large the room is and small items will get lost in this room. Also for you ceiling, don't even consider a 54 or 60" size. Start looking at the big fans if you expect any air movement.

Is the orange wall load bearing? No, and I had a contractor double check to make sure :-) The top cracked a little shortly after I prettied it up, though, so there's SOME weight on it! That's a concern, but it hasn't cracked any further so maybe it was just from house settling? I also have no idea why so many want to put a fireplace in, unless you plan to use that sucker 6 months out of the year, its a space eater and a room definer. In my area, 4-5 months would be likely; October or November through February or March. Snow in February is common, sometimes it happens in March, and rarely as late as Easter. Our last frost is typically early-to-mid May, though, so cold nights can be as often as 8 months out of the year. I originally wanted to put in a gas fireplace as a heat backup when the electricity goes out. I'm still thinking about that, but I don't have a great place to hide the gas tank so I'm not sure. The electric goes out enough over the winters that I'm seriously considering solar panels, too. Last but not least, in theory I could save electricity by using a 1500W fireplace to heat the main floor throughout the day, and only turning on the heat pump near bed time. as to island, id skip that and work on a peninsula instead I'm totally open to remodeling the entire kitchen, too. I like the cabinet style, but the refrigerator is against a short wall that keeps me from opening the right door completely! That was fine 20 years ago when I had a regular fridge with a thin door, but now I have French doors with the door-in-door compartment, and with it fully open I can barely get into the main section! I could also put in a corner cabinet to connect to the peninsula, giving me more storage :-) I'd want to keep the cabinets beneath the peninsula, but I could always make that part of the counter a little deeper to create a sitting area. Maybe even some pendulum lights over that counter to define the kitchen area better...
