I can't answer the first question, but as for the second one: The reason the devs didn't put in those items (I'm guessing) is because a lot of people have them and therefore the devs didn't want people to feel like they are paying for them again. That's probably why they added the shuttle into the pack.
You are getting at least 1440AT worth of stuff for 1400AT with one item they generally don't sell in the C-Store. (Prices based on similar items on C-Store)
Interior: ~120 based on cheaper bridge packs
Shuttle Pet: included with Shuttle
3 Uniform Packs: 3x240
TOS Phaser: Free
They threw in the Phaser and I'm sure the Interior combined with the Bridge would raise that to close to 400AT. It's a good deal over buying the individual parts by themselves.
