Can someone help explain the leveling, class-changing, and mastery progression beyond what is currently listed on the main page?

I understand that the progression is to get to levels 5/10/20/30 and then to change to the best growth class available ASAP, but I am not sure what comes next. Stay in that class until the level cap? And then once you are at level cap (which is what?), you can go about mastering other classes?
Aside from the Master Ability, does mastering classes provide any other benefits to other classes? Would there be any benefit to mastering every class on a character?
