Not all items are eligible, but everything from the crates should be.
Generally with typical equipment loots or vendor purchases, if it doesn't say you haven't then you have learned it.
You should be able to search for the item by name though if you filter it to the slot and weapon type if applicable first, while you are logged into a relevant character.
As a general, but not entirely inclusive rule that if it can be soulbound, either Bind to Account, Bind in Pickup or Bind on Equip and Green/Uncommon or higher then it should be allowed.
