I think with 8 panels, you'd be able to include most every major table in the book. The obvious ones are the ones in the back, plus the FTL travel tables and maybe the technobabble tables?
A panel with stripped-down stats for a bunch of easy to reference foes might be useful.
Combat modifiers.

Random encounter tables? The space on is useful.
Extended tasks.
Oh, here's an important one - list of statuses/conditions! They get looked up a lot!
