Not that my opinion is necessarily worth much, but:
Absolutely push design up into the T20 Ref's Manual. Leverage what's already out there, please -- no need to create work, there's always too much to do.
One vehicle book seems enough. I suspect civilian vehicles are just not sexy enough to warrant their own book. Perhaps as little as a note specifying what's omitted in civilian variants.
Similarly with the ships book. The division doesn't seem worthwhile? If you must, a "small ships" catalogue versus a "big ships" catalogue.
Atlases, aye.
Gear, oh aye.
Location books, an awesome resource. Find a graphics guy to do floorplans?
NPC books, i.e. "Patron and Nemesis List", another awesome resource.
Alien Sourcebooks, yes of course.
