If you haven't already, play the quests 'The War Within' and 'The Sacrifice'. This should answer at least some of your questions, without anyone having to put spoilers on this page. ('The Limbo Theorem' might also help to answer your last question, if you consider the implications of what you've learned so far from the other two quests.)
