Could the PC use one of his skills / proficiencies from background etc for this?
Nope. None of the skills and proficiences from backgrounds grant weapon proficiencies.

I'm just wondering how he's getting the Crossbow Expert and Light Armor Expert feats. He already has Skulker, too!
Also: What does Pot of Greed do?
Not necessarily. The modular nature of 5e means you can let players take responsibility for their characters and the GM does monsters.I don't want to sound like a jerk (I know you said you were new) but did you read the class chapter? All your problems with your rogue player could have been avoided if you bothered learning the abilities of the rogue, because it is also part of the GM job to know your players characters as much as them. If not, how are you supposed to know if you build balanced encounters?
