I'm the last person on earth to say this, as you well know, but set aside the academic hangover as much as you can while you make the decision -- whatever else it does for you or doesn't, a library degree won't suck out your soul through your tear ducts or keep you around for untold years while you slowly come to the realization that you've fallen into some existential abyss. It's just not that kind of grad school.

Unfortunately, I don't have any answers for the more practical concerns.
