I don't think waiting until you are Divine will make any difference; there are no survivor skill books, that know of.
There are a couple spell book names than can teach different skills. Sparks can teach either Lightning of Elemental Hail (or was it Elemental Strike?). I don't recall the name of the book that can teach Deadly Disks or something else, but it should not have the exact name as one of the skills.
