Materia is fine, it tells you what the stats on it are, what catalyst you need, and what crafter you need. You really don't have to worry about being picky until you're working on your endgame gear. Catalyst-hunting is the only negative thing about it. There's no in-game way to know where certain catalysts are and Fingerprints of the Gods is really freaking random. It needs to activate more for lower tier catalysts so the price on the low rank catalysts will drop and newbies can get into it.
