How much do those books cost though? Assuming you can kill the absolute minimum and get all 5 stones by level 4, will you even be able to afford a book?
I guess you can get a handsome amount of gold just by collecting paintings, golden plates and cups from Black Cove/Cyseal/other areas I haven't reached yet.
Oh by the way. A quick way to kill the ghost pirate is to get 1 or 2 points in telekinesis (depending on how many you need to be able to put barrels in your inventory), get scoundrel on both your characters, sneak one to the ghost. With the other one, sneak to all the oil barrels you can find and pass them from your inventory to your other character.
Then, congregate with your other character who should have a good 10+ oil barrels lying around him.
Now surround the pirate with these barrels using your telekinesis character.
The explosion should insta kill him. Then just sneak away to avoid fighting the skeletons. Don't forget the bloodstone in the chest!
Note: This method is not tested! When I did it I had used up quite a few barrels so I only had 3 more for that fight, which reduced him to about 50% health. I am just assuming that ~10 barrels would easily insta-kill.
EDIT: I just thought of something. Couldn't you get companions and have them do all this dirty work? If your other characters are far, do they still get xp? At least you could kill off ONE of your main characters so s/he doesn't get xp.
