My thoughts;
To comment on one of your answers, Set:
And we still have no idea what Christopher's plan was. He made it clear to his son that he wasn't going to their home-world, but some other planet entirely for some reason that wasn't made clear. Perhaps the ship that came to Earth was only one of two (or more) ships fleeing their home-world, and he's headed to one of the other colonies, in the hopes that they've been spectacularly more successful in the last 20 years and can help him rescue the prawn refugees on Earth?
Unless there is another point where Christopher tells his son that they won't be going to their home world, I think that the new home Christopher is referring to is actually the new camp the Prawns are being moved to. He even points out the row of tents in the pamphlet and tells his son this one of those tents could be their new home. He'd finally resigned himself to losing the fuel forever and not being able to leave Earth like he'd planned.
There may be another point in the movie where they have a discussion about where they were going, but that's the only one that I could remember when reading your comments. I've definitely missed some things that posts here have cleared up for me though, so maybe this is just something else.
