Similarly we can say that the language of this ancient civilization remained and now forms the basis of the common tongue across the galaxy (dubbed as "Galactic Basic" or whatever).

This is a good idea. I like this idea.

I'm not so hot about the ship classifications thing. I mean, civilizations could easily have different names for different ship types (Like battleships that can only fire missiles that they call mines), which would spice things up a bit. I suppose we could instead have universal size or weight classes.
