I've looked at the fabrics. Fabrics are SO hard to choose, for a lot of reasons. One thing I learned when I was doing this for myself was to absolutely NOT select a fabric without seeing it in person first. They look completely different in person. You want to hold them up to furniture in the light of the room in which they will be. Light affects colors and fabrics dramatically. If you're doing this strictly online, you should be able to request swatches from Smith Bros. Better still, if there is a retailer near you yo can actually walk in and look at the large swatches and take some home, do so. Other considerations. Cleaning. It is my understanding (someone please correct me if I'm wrong) that the fabrics that are 100% man-made materials ,i.e.: polyester, acrylic, etc., are very hard to clean, that you want a fabric which at least has some cotton or wool or whatever in it. Also, you want to feel the fabrics so you'll have a sense of how comfortable it will be to sit on. Will if "feel" too cold in winter? That sort of thing. And wear: you don't want to have to reupholster the pieces in five years! Re: the fabrics you picked. Love, love, love 334211, the chair fabric. Beautiful. gorgeous colors, and it'll look stunning on that carpet. You absolutely can do the entire chair and ottoman in that fabric, and should, IMO. I love the chocolate brown/muted gray/blue color combo. Didn't particularly care for the second patterned fabric you chose for pillows, but that's just a matter of personal taste, of course. I do think the two patterns clash. re: the sofa fabric. I'm really not sure about it. It strikes me as being too dark for the carpet you've chosen, but it's hard to say w/o seeing a swatch in person. I think that with such a dark carpet, I'd want a bit more of a contrast. I think you're right, though, to go with a "railroad" pattern for the sofa, rather than jacquard or floral or whatever. I believe in being conservative with sofa fabrics (so they won't get dated and need to be recovered fairly quickly) and dressing sofas up instead with pillows and throws. Okay, I've gone through all the fabrics, matched them back and forth by using multiple windows, and this is what I came up with. For the sofa, purely by coincidence, I kept coming back to #329511, and it's the only one I settled on. It also has some cotton in it, which is good for sofa fabric. It'll look stunning on the dark brown carpet, and it goes very nicely with chair's 334211. The herringbone pattern gives it some texture, which you will like on a large piece like a sofa. For the sofa pillows, I love the Palm Island counter fabric, 334311 OR the same fabric you'll have for the chair, 334211. These fabrics contrasting with the richness and starkness of the deep brown rug will be gorgeous, in my opinion. but again, ALWAYS look at swatches in person before making a final decision. If you were to get a set of wood slat blinds for the two windows on each side of the fireplace, I think that would be the icing on the cake for that room (see link). Room with this color combo and these blinds would be warm enough in winter, cool enough for summer, serene…just beautiful, IMO. and why won't you use the wood-burning fireplace? Oh my! You must! Just remember to close the flue in the morning so your heat doesn't escape up the chimney! It's gonna be gorgeous, Carol! Here is a link that might be useful: Fireplace window blinds

Does your FP work in both rooms? Is there another option for guests to get to the DR without those two openings? Your large sofa is in a good place but it (and the sewing machine) seem to be blocking that doorway to the DR. I'd consider closing at least that one, if not both openings. The loveseat needs to be replaced with a pair of chairs and a table. That will eliminate the bulk that is cutting off the window side of the room. Consider placing a game table and chairs in the window area. Another option would be to float sofa facing the FP with two small scale chairs flanking it with a coffee table accessible to all the seats (18" or less from each.) A sofa table could face the entry, and then the window area could still handle a small game table and chairs. If you're not into games, a bench under the center window would provide additional seating. In any case, I'd find another location for the sewing machine, and consider end tables. They should arrive 1" above or below sofa arms (same for chairs with a side table.) Here are a couple of inspirations for a game table.

Something like this.... Furniture focused on the fireplace not on the walls. Float sofa and chairs. There are several ways to place the furniture without having it against the walls.

Put the TV on the ledge next to the fireplace. That should put the center of the TV screen on eye level with a seated watcher. Place the recliners facing the TV/fireplace, and put an end table between them. Treat the small space as a separate room. A chaise could make it a good place to lay back and read.
