[Mongoose Traveller] Help me navigate the MongTrav supplement line

Which book(s), if any, offer interesting and useful tools for the enterprising ref who wants to:

• Create sentient, playable, non-humanoid alien species.
  


• Create menacing, NPC-only alien monsters.
  


• Create big honkin' spaceships without going crazy and/or spending a lot of time.
  


• Run mass combats involving planetside armies.
  


• Run mass combats involving massive fleets of big honkin' spaceships.
  


• Run a game of very ambitious PCs carving out political and mercantile empires among the stars.
  


• Run a game of Traveller without FTL, with PCs flying generation ships and using anagathics and cybernetics to survive the long journeys and deriving the profit margins from that crazy old Paul Krugman paper.

Looking for stuff that's available/in-print and worth my gaming dollar. Biased towards official, but good quality third party material can rock my world too.
