How much SP you have is listed in the bottom right of your screen near your experience bar.
Far as how you get SP, just by leveling up I believe. There seems to be certain incriminates in a level where you'll get an SP point. Other than that, some quests give SP books which you can use.
I don't believe it's possible to max every single skill in a subclass. There are a lot of skills, be it passive, general or hidden. Planning your build beforehand is probably for the best.
"There once was a boy who dreamed of being a hero. Who believed sincerely in the battle to banish darkness from a world of light... but light and darkness are equal... and where one exists so too must the other... and when the boy finally realized this he had taken the first step toward being a true hero."
