Since it's the largest piece in the room, I think you should start with your sofa and work from there. What colors are available without doing a custom job? Maybe you can find a color that's in your painting or map. Bring home some decent size fabric samples and we can help you better. After you get the sofa squared away, I'd start looking at laminate. I think it would look nice if you had all those pieces under the laminate uniform in color so it seems less broken up and busy. I can't tell if they're stained or painted on my monitor. You have a lot going on around the room with your bookcases so I think I would go with something solid or wood grain for the counter tops. When you start to look at laminate, go to several places because when I was looking, I found that no one store stocked all the samples available in the lines of say, Formica and Wilson Art. If you call the companies once you've narrowed down your selection, they'll send you larger samples than those little pieces at the stores. There are others here more knowledgeable about window treatment options than I am ,so I won't go there.

I personally would go with the beige. Its a nice light neutral, but the warm tones look great with the flooring and the accent chair color. White will get a bit washed out with the white leather stools, and the grey may end up being a little too on the cool side.

The color of the sofa pictures is the same exact color however I changed the pillows to the fabric attached. The fabric is a grayish color. I need help picking a paint color. The room is going to have carpet likely a light beige or gray.

Blue. I also agree a white/cream would work. Light colors still make me nervous eBen though there are lots of performance fabrics. I also would hate messing with slipcovers ymmv. I think color couches add more interest.
