I can only answer half of your question. You don't need Custom Edition to use mods, although Custom Edition is much friendlier concerning mods. The mods for CE are built right into the maps. You don't have to mess around with replacing/renaming files, using weird hacking tools, and all that crap. You just download a map, install, play. As for installing this Halo PC mod you're talking about, it might help if you posted which mod and where you downloaded it from.
