I also cant open the jewelers bag?
Any tips?

Hovering your cursor over the item and pressing 'E' is the hotkey for interacting with Jewelcrafting items while in your inventory. That'll open your bag and show your weapon slots so you can put gems in them.
Can only have one Boss-Gem equipped at a time.
