How can I get started with FaceTime on a Macbook Pro?
FaceTime is stored in /Applications/Facetime.app and all the settings and preferences you need are available from within the application's preferences and help menu.

Here is a nice troubleshooting article that might help.

Also, since you have a new mac, you should have 90 days of paid support to get you up and running. That support is really helpful for getting oriented since it's hard to expect a new user to know where to look for details on new hardware and potentially new software.
