Like mclericp said, I don't think there is any tutorial that teaches you the new things of BNW, but your advisers will tell you alot about the new features. Just make sure you have adviser input set to the "New To Brave New World" setting in options. It will also give you links to more in-depth information about the new systems. Also read up on the new features in the Civilpedia, and you'll be used to them in no time.
