Does Bill have permission to slip you vague facts about your previous self or world?: Yes, because who doesn't thrive on total confusion!
Is there anything specific you would like him to focus on?: HE HAS A DOG NAMED JOHN WHO HE CONSIDERS HIS SOULMATE so clearly that's an important fact. Being a hero? Flying? His catchphrase, "thanks and thanks again!" is good!
Can Bill mention any random details of your world to someone else? : Personally don't mind, but since there are others from the canon, I'd defer to their preferences. (Ivan and Pao-lin in Flowers Over Bones.)
Is there anything you absolutely do NOT want him to know: Nothing comes to mind. He's had his mind messed with in canon aaaaand also got his ass beat by a telepath, so it's not like he hasn't been intruded upon before D|
