Look st the Search box ^ up there. Find a local Pro to hire. The forum is not a substitute for the needed involvement of a paid professional. This isn’t where to find the best turquoise pillow, or the interminable search for a backsplash tile. Your needs are too broad and numerous. You want a whole space plan, and a full design. Hire the Pro who can do all of that for you.

Are you going to replace what you presently have in the living room? If so, a scaled down sofa and chairs that are easily moved is where to start. Your furniture is too big for the space and so is the TV. I would venture to say that space you pictured is a hall and not a dining room. Any chance you can move that table either into the kitchen or into the living room? If you like West Elm, visit their store or look online to see how they group rooms and use the space. That would give you some basis from where to start.
