Greys would look good in these rooms. I wouldn't paint the paneling. Rather than a mirror over the fireplace a large scale painting would look good.

I would suggest you take out the cabinet that is to the right of the stove and use it elsewhere in the house -- perhaps in the bathroom or dining room with a hutch above it. Then, I would suggest you have someone install a lazy susan cabinet in the corner between the sink counter and the stove, meaning you would move the stove down a bit and have a small cabinet/counter top to the right of the stove. I would suggest you have the cabinets refinished in white and then paint the walls a pastel you like. If you would prefer white walls, then add white-painted crown molding and paint the ceiling a light neutral blue, such as Sherwin Williams Niagara Falls Blue. Then, I would suggest you choose a favorite accent color and use this sparingly in accessories like towels, pot holders, small vases or floral arrangements, and a valence above the triple windows. For a genuine 1940s look, you might have white ceramic square tiles with a rectangular red border installed as a back splash behind and above the stove. If you are replacing counter tops, I would suggest a light color such as white with a beige or light grey vein or striation for some sort of pattern. You might be able to find the same color and design in floor tile OR opt for a wood floor as another poster suggested.

I think it is awesome to give a piece of furniture a new life. It is sometimes a bit daunting to take a paint brush to a piece made from genuine old timber but if you are going to get many more years of life and enjoyment out of it I think it is better than dumping it. I believe it shows your love. jbof4 I started with a heat gun to remove most of the many layers of paint, (some are easier than others to strip this way). Then I used an orbital sander and sanded and sanded and sanded. You might also try liquid paint stripper although I find this very messy. I believe you can also get them professionally stripped. Good luck with the resurrection, go for it what have you got to lose.

There are some great comment here, but my take on this would be if you are going custom to take your time and look around. Many designers offer different takes on each person's preference. The colours you have are good but I'd personally would opt for a more warmer cream, with a self print pattern. I would also suggest pinch pleated curtains and not pencil pleat as you have currently, pinch pleated curtains will give you uniformed pleats from top to bottom. In addition to this I would suggest you use blackout linen to prevent light to enter the room, and possibly interlining so that you retain some thermal properties in your fixtures. Having custom made curtains are a lifetime choice for most customers, take your time and don't settle for the first company you come across. The space above your bed i would possibly add a sheer fabric roman blind which is slightly see through but enough to give you privacy if you bedroom is situated on the ground floor. You can also get the a roman blind to match your new curtains if you'd like a more repetitive theme in your bedroom. I would suggest if you do opt for a roman blind, and you are looking for a good qualities add blackout linen.
