When you go up levels you allocate those points. Every few levels you get to pick another attribute for your character. One of the skills you can chose is the First Aid skill (am cheating and found this on the net). You can use that to heal yourself by the way. Resting also heals but sometimes you will be interrupted by villains. There are also potions etc that you can find in the game.
There is a beginning "simulation" in the manual that gives you a start up on the game - how combat and how movement works.
