Naw, some of the ai can be trusted more or less. Yes, they might get a little frisky with you, if you have a really small army. However, if you maintain a respectable sized force, you can live with some of them. Also, some of the computers don't really hold a grudge if you win a war they started.
Religion is a fun thing, my advice though is decide early on what you want to do with it. Do you want to make cash? Do you want it to feed your culture? Or aid growth?
