1. which ones, if any, are worth buying?
2. what exactly are beasts, avions, fiends, and constructs?

All of them eventually. I'd work on getting the first 3 on that list first though.

Honestly you should farm until you can buy all of them. All of those you listed are monster types you will eventually encounter in the game, and basically all those books increase the droprate of rare items and such.

I just recently got them all cept the last one, Sages Monograph.
So far i guess i cant tell the difference in drops but im sure its there. I made enough money to buy them all in about an hour and a half time, like 120k, farming the hell out of Ozmone Plain/Golmore jungle. Just burn through everything, panthers and marlboros drops some nice stuff too, Marlboros can get annoying fast with sleep/poison/slow etc, but if u kill them fast enough they wont get it off. Iron Carapaces drop from the horses in Ozmone are expensive sells also.
