Here is some information on the materials.
Most importantly - White kept to 70% grey, Black at 9% black.

In the SketchUp material editor use the HLS type color editor, and slide that "L" - "lightness" slider down the same amount for all your textures - slide it down approximately 30% so that uniformly you make all your materials relatively darker. Most importantly all of your lighter materials (like the texture in your scene containing white, but also some other colors) but not only that - be sure to set all white surfaces like ceiling and walls in your scene to 70% grey.

Why?
This is closer to real-world physics and proper gamma space for your textures/colors/materials.
This means that the calculations for the light bounces will be more accurate, and so the error check that is built into the rendering algorithm will reject less of it's calculations and have to correct less, which means it will find a good result more quickly.

Be sure your light powers are set to real-world realistic values, if you find yourself increasing light powers more and more, then it could be that something is wrong. Instead, you should use the Post-Process tab in the Render Dialog (little button at bottom of dialog box) to adjust the brightness of the rendering. Try adjust the Light and Dark values found on the Linear tab inside of the Post-Process Dialog - it can give better results in many cases - especially with interior renderings when interior lights are shining directly on nearby light-colored surfaces.

After you feel you have gotten this set up right, you can then individually boost/decrease the relative "lightness" of each texture. You should be comparing the lightness of the rendered wood and the rendered white walls and other adjacent materials. It is a balance between the artist's eye and actual physics of light in this phase.
