If you can paint the kitchen walls and trim the same color, then the trim will look like an extension of the walls. If that is the case, I don't think you need to worry about the stained trim elsewhere.

That might work I would discourage the chaise on the sectional just do an ottoman same sitting comfort but much nicer seating when you company. IMO thi s is ahuge space that is poorly laid out the DR table needs to be about 3x the size I would put it infront of the patio doors off the kitchen then you would have a huge LR with a couple of seating arragements one in front of the fireplace and one for T.V viewing all pieces that can be moved when you have a crowd.We have a large LR and I puposely bought piecs that could be rearranged for different looks and purposes like the Christmas tree for instance .So I have 2 sofas, a chairs that do not match the sofa or each other but work in the space a long bench that can be moved easily wherever I need it I really dislike sectionals because they are so site specific and in your space I think if possible think many useful pieces that can move easily .

Ignore the critics that think you should have new everything for every room -- not all of us have that budget. Don't discard your furnishings. That you have exercise equipment in this room indicates it's not intended to be a formal living room. While it may well be that not all your furnishings are on the short list of items most of us want to put in our the living room for creating a good first impression -- they're certainly not out of place for a family/activity room. You might want a larger cabinet on which to set your tv in no small part because a taller cabinet will be more comfortable to watch and a larger cabinet with doors would give you media related storage space. With that in mind, if you're wanting to change this room on a budget, sometimes you can find an old hutch or bookcase suitable for use as a tv stand from an "antique and more" resale (used stuff) store, Habitat for Humanity Restore Store, Good Will or a local charity thrift store that will serve your purpose When you are out and about with a few minutes to spare, wake through these and see if something catches your eye. If you are careful not to collect junk -- if you know the measurements of your room/space before buying anything and buy only what you will actually use, then such trips will not be wasted time. Good hunting.

I'd use some shade of warm white in the space. Keep away from grays and stay in the neutral to warm tones so it works with your other finishes. Are you removing the drapes and rods? You don't need them with the shutters. If something is needed on the French doors, add a clear UV film for the sun, or a simple white/cream drape if you need privacy. You may want to update your lighting fixtures.
