You have gearsets though there is no collection for them yet(apparently being worked on though). Basically certain dungeons drop certain gearsets. Infantry set, Colliseum set, and so on.

As for a good resource for minions and mounts:

You enter you character name, your server and hit the button and it tells you what you have, what you don't and how to obtain it.
