Yeah, we've already shown the twins both having considerably more understanding of the Force than in canon, which should make Dagobah and the Cloud City rather interesting to write.

You're right about Obi and Padme, that was our intention from the beginning with Padme being alive and now with Obi as well. We never meant for them to be tagging along with the kids, so I don't see the fact that they're alive as a bad thing for the kids. I mean, if anything, having parents around will *help* them.

In a sense, Luke fulfills his destiny by destroying Vader. He then goes on to found the new Jedi Order. Fulfilling one's destiny doesn't mean death, necessarily. If Ani was going to die, he would have died on the Death Star. It didn't happen because the story seems to have other plans for him. So, I wouldn't worry about it.
