1) I would switch to serfsom during the ga. This isn't the game for it long term, but it's a good ga civac. I think you already have a good shot at a soonish 2nd ga so I wouldn't use caste, but then again I hate caste (a lot of people do use for purpose you described). But ya spread religion to high prod cities first to further spread.
2) do not close borders! Do you want to start a dog pile against you! I'm already a smidge nervous because of incoming ap. If the glh player is clearly leading that is one thing. And xist is protective which is one of the reasons I like pro is that glh leads to less closed borders from others.
