Your confusing two things, though they aren't unrelated. Changeing the axis will, to some small amount, look at the position of the light in addition to the position of the geometry. The actual location of the light doesn't matter once the pivot is set, but that's a complication that you shouldn't worry with. The one for the firepoint is also more or less the same, except that you appear to be taking advantage of autogen. I never did (easier to add my own data in the days when I was creating ships that could be edited in Modelview without it crashing for lack of memory, and I've never been terribly impressed with the results of autogen) but that shouldn't stop you. If you're just using it for the location, it shouldn't matter though.
