Knowledge sharing for writing browser tests - with Protractor, to run in Sauce Labs, good docs and examples, etc

I need probably two more full walk-throughs of the browser (acceptance) testing setup before I will understand it fully :)

The big questions in my head:

1. How are the files & directories structured? I.e., how do all the pieces fit together?
2. What base concepts and principles do I need to have down cold if I need to write a new test and there isn't an obvious example to model it off of?
