Keep him as a house cat there shouldn't be a problem but you will definately need to have him neutered before he starts spraying. You could look into this now as some vets will do it earlier than others.
I would definately say he needs a friend to snuggle up to at night.
I know where your'e coming from about pets in the bedroom though and there is no real reason to change your mind over this.
Goodluck!
