I love white cabinetry and woodwork, also. However, sometimes it just is not feasible to begin painting existing wood built-ins unless you are willing to change out many other things so the entire house 'flows'. These cabinets could look more attractive and updated with some shelves removed, and using fewer updated display pieces of varying sizes. Update the fireplace screen, to eliminate one of the 'black holes', and update the ceiling fans. Move on to other accents. For example, change out the pair of black chairs to something a with a little more character, like a new fabric print that will pop against the fireplace and built-in. You don't have to spend a fortune. A couple of armless chairs from any number of inexpensive sources could do the trick. There is more that could be done, of course, but start with a couple of smaller things, then expand as budget allows.

I have the same exact senario.. only I have more wood than you do.. After researching I'm going to do.. which in your situation also I think would look nice. I personally love contrast. I'd paint the bookcase except for the counter, top boards facing us and fireplace white. At the end you can decide if the top boards need to be painted. but might make nice contrast. Some other suggestions would be to paint your fan black (the gold part). It will update it. or like some suggested a new one. I did that and cost me 5 bucks. Go from there. After that material and starch it up on the back of bookcase. Use any design/color you'd like just don't make it tooo light. The beauty is you can take down anytime or get a new design. I think once you do this your room will pop a bit more.. however.. after that and only then would I paint that beautiful wood trim around the room. Personally I don't think you will need to paint the rest of the room after this because it will bring a focal point and the updated contrast your looking for. think it would balance your room out without spending $$ and alot of time.. and of course once its painted .. you can't go back to wood. You might also consider staining the parts you left wood darker if you still want more contrast.. hope this helps.. please post pictures whatever you choose..

I have the same exact issue.
