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!

#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.

Is the indent in the wall where you have the TV now, supposed to be for a TV or is it to be a closed up closet?? You could switch the room with living area where you walk in but then you cannot wall mount the TV due to windows. Plus you might like eating near windows for more lighting drama. Also , now seeing your hall , I think turning the dining table 90 degrees from how I placed it, would fit better in your space. You could consider an area rug under the table as well , which would help to define the space when you enter. Also keeping a runner and a vase with either fresh ( or nice fake) flowers on the table, will make it flow better with the living room area furniture.

I would use the greens from your bedspread. Since you have green in the bedspread, and brown and white tiles, those 3 colors need to be your focal point. So I have painted your wall a bright olive green ( the darker color in your bed spread) and the ceiling either a brown to match the tile or a white to match the rest of your ceiling. then or I think this last one is a little tamer . But you should be able to paint over the tile. WHAT kind of tile is it? If it is ceramic you can paint it.
