These are a tough find! I do know that they get a lot of furnishing items form Mitchell Gold http://www.mgbwhome.com/. I could not find the lighting on there, but, you may want to occasionally check their website. They are going to set up a Good Wife furnishing collections soon :) sorry I couldn't help!

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

i agree with lighting trends on the peach ,here are a couple of palettes to choose from note your lighting will accentuate the mood and can give the hue you want , but definitely go for a neutral , the colours are from sherwin williams, benjamin moore , behr , and kelly moore
