Well, what you've managed to get yourself into is the beginning stages of hedgie addiction. I can see the first signs already (and they are good signs): you're considering how the world appears from your hedgie's point of view - it's kind of scary for a little guy.
It's pretty normal to have a huffy ball of quills - particularly at first. From your hedgie's perspective, everything in his life has just changed: new cage, new bedding, new water dish/bottle, new water flavor, new food dish, new toys, new scent in the air, new humans... Be patient, be quiet and subtle in your movements.
If your hedgie is making machine-gun huffing/hissing be calming to him - turn the lights down low and quietly sing a song that you would sing to a baby. Personally, I go for "You are my sunshine" but replace "sunshine" with "hedgehog."
If he's attacking, it's probably because he thinks he needs to defend himself. You can pick him up with a piece of fleece - scrap fleece from a fabric store will work wonders. For you, it'll help protect your hands; for him, it'll provide a place to snuggle and hide when he's in your arms; for the both of you, he'll become better used to your scent because the fleece won't block that.
