I don't have the game so I can't answer on size
No, it doesn't have iCloud support and save data wont transfer between the iPhone and iPad versions.
GameCenter sandbox is used by beta testers because unsigned code isn't allowed to connect with the real GameCenter so it is segregated.
Sandbox levels usually refers to levels with open goals that allow you to play freely. A level that encourages you to beat your flight time is a great example, you can test out all kinds of new builds while trying to meet that generic goal.
