Just got mine yesterday, so not much experience in the area, but I looked at several and not one of them even threatened me. Picked him up to take him out of the tank, put him in his new one, clean out his tank after he pooped, put him back in, and nothin. He does still make me nervous, though, so I totally understand your concern... if you mess with something that has teeth, youre at risk of being bitten.
You could wear gloves the first couple times until you both feel comfortable with eachother. Then ditch 'em when you see how chill your snake is!
