I've installed the monster mod pack and its great but I have a question.

If I want to install the monster glow begone mod, how do I do this because the instructions say to put everything in the RAR folder in the data directory, except both have a mod folder. I don't want to mess up my monster mods I finally got working, how do I do this?
Do I go in the monster glow begones specific mod folder and put the files in my current mod folder or is there something else I have to do?
