Regarding your first point: yes yes yes. I hated shelving at first, but after about a year and a half, I grew to love it. It was always the first thing I did, even though I technically wasn't supposed to (I had other "more important" work).

Fun outcome of this: I can no longer sit in a library and do homework... my eyes inevitably wander to the shelves and I can't stand it if they're not straight. Blech.
