Why are you putting a blanket over him? When hedgehogs cant see what is touching them they tend to quill up. Is it possible for you to just put him in his cage and leave him to his business.
They "biting" at a new scent is most likely the begining part of him starting to annoint. If its not a finger tip it wont hurt for him to bite. Let him bite and see if he starts to tug at it and start to annoint. Then have a ball watching.
I personally dont believe you can "train" a hedgehog. Set a rountine yes. But not really to train the to do something that they dont naturally do. If you dont want to get bit.. dont put your bady parts by his mouth.
