Umm... whatever she learns about living life from Christianity won't hurt her. Especially at her age, its mostly stuff like... be nice to people, don't steal, be honest, forgive others, and sermon on the mount stuff (be kind, gentle, caring, etc.).
What's really dangerous are the people she'd be around, I guess. The church is more dangerous than Christianity/the Bible. Eventually when she enters her teenage/rebellious years she'll start to question people in authority (including the church/her religious upbringing), and she'll decide for herself. I wouldn't worry too much about it.
Edit: Bottom line being-- its fine to have the church instill these moral values at a young age, its what you'd probably be trying to teach her anyways. When she grows up, especially since she'll be seeing both sides (I'm assuming you're not Christian), it'll be pretty easy for her to choose for herself. Yes, you see "brainwashed" children of the religious right, but i'm assuming they have both parents pushing them in that direction + most of them will leave it in college.
