Well i've made any number of mods and think of myself as a bit familiar with the lawas governing them.

1: You would be in violation if you used models from a ST game that one would have to buy. Only people who had purchased the game would then be able to play it. Since that cannot be regulated you would be asked to remove the mod from public download.

(You clearly do not fall into this Category)

2: If you charged any kind of monetary fees for the use of this mod you would be in violation.

(again, no)

3: Credit where Credit is due (more obscure). if you in any way stated that you created Star Trek or the Star Trek theme you could be in violation.

(again no)

Mostly those are the only things that any body wuould get their hackles up about. In this case I dont think you have much of anything to worry about. The most you would have to worry about is a polite but firm letter from paramount asking you not to distribute your mod (i'd verify that it was true first).
