I would paint the entire fireplace including the mantel, all trim and shelving white. I like the Whisper White, but you must bring the paint samples into the room to see for yourself. The sheen on all woodwork should be semi-gloss, easy cleaning and looks crisp. I agree with painting the walls and I would paint the part above the mantel the same color as the walls, Summer Hue is beautiful, but once again I have no idea how that would look in your room. The walls should be flat most brands make a fairly easy to clean flat. If the fireplace were the focal point of the room, it could look very cool and dramatic to paint it a very dark gray almost black. But at least in this picture it seems that the entertainment/shelving unit is the focal point. hmm .... better stop while I am ahead.

The wood is beautiful. To me, the wood has an oriental-Japanese-inspired vibe. This wall's paint is nice, if your can match. Here's a method of choosing wall paint: http://www.lindaholtinteriors.com/2011/07/testing-wall-color-101/ Can you keep just the curtain panels and remove the sheers? At a later time, a non-patterned curtain panel the color of wall. I saw the art and I think it is OK, but not for this room. Perhaps in a bedroom? I don't understand the theme you have going? Giraffes? Clocks? If you like clocks, remove the giraffes and buy something like a large round wrought iron "clock". Note also the rug, pillows & throw as inspiration for your room. Perhaps the TV console in a lighter tone wood like their end tables (your room = too much black).

I like the 4th one the most, however it is very difficult to see the shades as they really do not show up in your photos. Look at lamps Plus.com 'sale' . be sure to get ones that are between 26 & 30" tall. Your side tables can be different, in fact should be, but the lamps should reach close to the same height. No more grey please.

Oh, I really like that last one--the gourd-like look with the mercury glass base and black shade. Now, a black shade will really direct the light to a more finely concentrated degree than a white or lighter-hued shade. If that worries you, definitely consider a lighter shade if you go for that lamp. My second favorite of these three would be the first one!
