to answer your question, if you set lights and shader gamma to 2.2 it means it will de-gamma the color inputs of your shaders and lights for you, just like setting the texture gamma to 2.2 will make it de-gamma any 8 and 16 bit images you plug in. (it will leave float images linear just as it should)
I used to keep them all to 2.2, but there isn't actually anything wrong with leaving the shader and light gamma at 1.0, if you don't de-gamma your textures they will obviously turn out milky in the final render, but the shader and light colors are just... colors so if you don't de-gamma them it just means you will have to adjust them differently to get the desired result.
