I would not mix LED and CFL they have different looks and LED s are much cheaper to run. You can find a fixture you like and switch out most with LEDs, we have been slowly changing all of our halogen lighting to LEDs now that the LEDs come in higher wattages. We have 70 halogen lights in our house so I am doing 12 at a time, love the change. I like the fact that you can have a lot more lights off the same circuit too.

I personally think a black and white room is sharp and provides a unique look. I understand if you want some color on the walls so I attached some other spaces with paint colors you may like. The cool blue is great with black and white as is a cement colored gray.

It should look great but test drive a few blues they can change a lot in different spaces.

is bedroom 2 the one to the right of the dining room? the bathroom there is showing a basin in it. yes? so you want to know, aside from the basin/sink in that bathroom would you also like one in the living room dining room itself. i don't see a need for another one, if the kitchen is right there, and the bathroom is right there... having an additional sink in the dining room isnt something i understand a need for.
