Like I told Zeroth, you're free to make whatever changes you want to your CS at this point, since nobody's getting "officially" accepted until the OOC goes up. If you want to swap careers, you can do that freely at this point. After your sheet gets accepte though? Then you'll have to go the Remram-way and actually [i]learn[/i] and [i]train[/i] new skills.

There's no set standard for tomes, and they're really only called that because fancy wizards and sorceres with big egos are the ones who wrote them. They're just 'books' really. And as for an entire book being needed for, and to learn, a single spell? Suspension of disbelief is my answer there.
