Hey KilsonX,
1. Through scripting can I take the players units and move them to a new map?
1b. Can the status of the first map be saved and reloaded by the script?
2b. If so how many sub maps would be possible?
At the moment, there is no in-game scripting in the way you are thinking about. It may well be added in a content update later though.
2. Can phase lines be turned on and off through scripts?
(See above) You can make a fully connected map, which is pretty much the same thing as not having phase lanes. You'd probably want to turn off "show connections" in the user interface though.
3. Through scripting can in game customization be implemented? *
2b. Can abilities and bonuses be added by the script? *
I'm not sure what exactly you mean by in-game customization, but pretty much everything in the game can be customized. Not scripted, but customized. And yes, that includes abilities, bonuses, UI, ships, planets, etc.
4. Can movies or Still images be used to convey a story?
5. Can the game be paused while giving the player a choice?
6. What are the Game over options? -- So if I wanted a player to lose if a certain ship dies or station?
7. Can planets be made to move? - Say simulating an orbital pattern.
7b. Are binary Systems possible?
Most of these things would require scripting, so they fall under "may be added in a content update". Orbiting planets won't be possible (it was originally in but banished for being not fun to play with). I want to make a binary system myself, and nearly had it all working but something else took priority.

Hope that helps.
