Someone who knows more about layout will probably say something more cogent about this than me, but I notice that some of your bullet point lists are indented, and some aren't.  Is that on purpose?

I think indentation is working against you on your short lines. You might consider using a different style of paragraph for those lines, since those short, declarative sentences should probably stand out.

I'm not sure what to suggest for a font. Is that Garamond of some variety? It looks quite nice, but I'm not sure “nice” is what you're after.

The bullets on page 38 seem close to the text that follows them. Furthermore, I'd make the paragraph indent (the whole paragraph, not just the first line) to the spot after the tab that follows the bullet.

On page 39, It seems like Front One and Threat 1 (why the change in numbering?) should be a little stronger. They're not the same level of information as Is called and Move.

I generally avoid centering elements on a page, but it's working here for you. I'm not sure why, but it seems quite good that way. Normally, it makes them float around irresolutely, but here that doesn't seem to be the case. I think it's because your choice of header font is so heavy.

I think you'd benefit from increasing the size of your outside margins by, I dunno, an eighth inch? A quarter? That will give you thumbspace and reduce the number of line orphans like in the Cast section.
