I don't think there's anything wrong with this if you see all the proper functionality. The file names don't matter, actually (at least for armor, characters, weapons, skills, I think).
For the GM mode stuff, you have the For GM thing set for the skill? It's one of the first options in the skill editor, when making a skill.
