All I read was the first post, so excuse me if I'm repeating what someone else has already said. I just need to say it before I forget.

As a theory, evolution is the most solid one we have, and we should stick to teaching it in schools. The only reason we should teach another theory is if it becomes more plausible than the theory of evolution, but nothing is. So evolution is what should be taught, no two questions about it.

As for including religious beliefs into it, no. I am a christian, but i don't think that should be incorporated into science when you're learning at school. You can mingle them together later. But as my senior year biology teacher told me "this is science, leave your religious beliefs at the door. It isn't about what you believe, it's about what you know." And you don't get and A in science class for talking about creation, you get an A in science class for talking about Evolution.
