I have question that's been bugging me for a while. If Bec Noir knew how the quest beds work (he brought Jade to hers after she died) then why did he stab John when he was asleep on his? Wouldn't that have just created another powerful enemy for him?

I’d argue that he doesn’t know how quest beds work and that he put Jade on her quest bed because whenever Jade would have a narcoleptic episode Bec would always put her in bed.
