As a brit living in the US (I know, different country, but still...) I used the equivalent site down here to download forms, etc. I needed MY birth certificate, the kids birth certificates, and other stuff like that. It was a bit of a pain, but not too bad. Good luck.

Children under 15 can travel to Canada, using a birth certificate, as long as they are NOT flying. If flying, they would need a Passport.
The passport is the best document to have. There are some items that can be used instead of a passport, but they are limited. See the page below for the detailed requirements.

According to the State Department of Canada: A valid U.S. passport, passport card, or NEXUS card satisfies these requirements for U.S. citizens. Children under 16 need only present proof of U.S. citizenship. Entry into the United States: When traveling by air from Canada, U.S. citizens are required by U.S. law to present a U.S. passport book.
So long as you had a valid passport, absolutely.
No, one can travel between provinces without papers or passport.
