#1 and #4 are related. In the OnRequestStart method, which is called at the beginning of each new event, the UserController checks to see if there's a UserRecord in the session scope, and if not, it puts one there. It then places that UserRecord into the event. This allows the rest of your application to be able to access the session-resident UserRecord without caring where it comes from. Take a look at the ScopeFacade.cfc and you'll see the advantages to using it instead of direct scope access. It's much easier to provide locking when you only have to do it in one place.
The underscore before the method names is a convention in many programming languages. Underscores are often used to identify private or reserved method and variable names. It is also to help avoid accidental overriding of those methods and variables.
