Texturing is something you really don't want to over think on a ship like this. I've experimented with hull paneling and stuff like that, though it really all looks icky. All you really need are simple maps with some "dirt" on them. I also like to put some very light grid lines on mine, in an attempt to mimic the look of the ship after someone drew them on (sometime around season two.) But, those are just my personal thoughts on this.
For the bussards: textures.
