Should I remove/de-activate the 00_A_Plutonium_Maximum_Effects_Edition_V1, or does this 00_Charly_Golf_effects mod overwrite all or part of that Pluto mod. If both Mods should stay in MODS folder, which should be on top?

You should just put a - in front of plutonium if you want to use CG effect mod. If there is a - in front of plutonium I don't think it will make a lot of difference if that one is on the top. I've got 2 different version of the effect mod above the one I'm using, but it is working properly.
