Is it ok to discard garo/makai gear? Can you store in Armoire?

They cannot go in the armoire, unfortunately.

Discarding depends on whether you have a full set or just a few pieces. Any complete set you have the achievement for can be rebought from the Calamity Salvager. Anything you don't have the achievement for can't be recovered, so you'll need to keep it.

Depends. If you got the achievement for having the full left side set for a class, you can get that class's gear from the calamity salvager any time you want. If you did NOT get the achievement though, anything you throw away is lost forever.

This is for left side items only though, right side items (accessories) cannot be reclaimed through the calamity salvager. The Garo shield cannot be reclaimed that way either, though there is a basically identical version of it that's obtainable through golden saucer.
