I have noticed that most of those sets all use the same vaccuform panels on the walls, just arranged in different configurations. The most obvious one to me being the one that is used repeatedly along the sides of launch platform. that shape can be found in almost every room, including the bridge and Tribunal chamber (court room).

There are several different ones, and they occasionally have variations of the main type. With a small library of panels you can build the majority of the walls and such of any room or corridor.

Right now I only have worked on one of these vaccuform panels.
The hardest thing about the galactica interior parts is the heavy use of rivets. If you model nice rivets your polycount goes through the roof. I was using this model to learn some "normal mapping" techniques. I achieved some promising early results.
It takes a lot of extra time to set up the model this way, but if you use it a lot it could reduce render times quite a bit.
