Reducing the cost of objects in this scene?

There’s 6 materials per book mesh.
In Statistics, Sum Tris is 1,322,106. Though this is an entire building, which the library is only one room of. Is there a way to see polys rendered in the current frame?
I haven’t actually tried static lighting them yet, since my light build times are already through the roof. If I switch them to static, it won’t be enough to see changes in performance right away, correct? I’d have to build lighting on everything? In which case I’d have to post results later tonight or tomorrow.

Edit: I took a screenshot of some stats when standing in the area of the room where most books are on-screen. I don’t have a rendering guy yet so I don’t have much of a clue as to what these mean, but hopefully they’re useful to you.

Edit 2:

That Mesh draw calls number is huge compared to walking around the rest of the building. Is this because of the number of books x the materials applied to them?
