I am using UFRaw with Gimp and energy saving lamps. The colour temperature of these lamps is quoted as 5000K which I presume I can set in the white balance. What I would like advice on, please, is what is the purpose of being able to vary the green setting and does this need to be set to any particular figure?

WB in RAW converter is a set of 3 multipliers, one for each channel - R, G, B. This is more flexible than color temperature itself. If you move green slider you will see how the picture changes.
