Yes that's the way to go with Minotaur, just let everyone (AND their pets if you have BSTs... very nice when they have IT slimes and pugils charmed and familiar'd).
The problem is getting to the library area once you're done. It also helps to have a THF to pick the doors so you don't have to mess around with Fomors. Or farm the keys well in advance and spend some time clearing your hate (You don't want any Fomor hate when you get upstairs >.>)
