You just have to start the game, and read what every NPC (non player character) has to say to you.
There are manuals for you to test at the beginning, for you to have a feel of how the characters' skills are going to be.
As for stats, there is a slight description of what they give you when you hover your mouse to them.
I've started the game pretending I'm a newbie, and I find it very easy due to the way the game is built now.
You may always drop a question here and there. Good luck to your journey!
