Sorry for not answering before, but I'm at work, wimvdb has helped you a lot :-)

For reflection I loaded BB EnvSphere deleted all nodes of its material and plugled a latlong env map directly to the alt difuse channel.

now for the color try to increase the difuse value and decrease the refraction value, always trying to keep the total of the value in 1.

of that dosent work for the dark decoration try pluging the texture to the refraction value since they are very dark (near to zero) they should lead to no refraction.

Sorry my english but I'm in a hurry at work.

Post your results please :-)
