That's a beautiful baby...sigh.
Welcome to the forums. BP's are one of the coolest snakes to have, IMO. They are docile, hardy, and the morphs are cool. They don't get too big. All in all, a great snake to start with. As babies, they may nip, simply because they haven't been handled much and it's a defence mechanism. It shouldn't hurt too much, if at all. My 1st bp never nipped all, but my 2nd, from a show, nipped a few times from fear and stress when we first had her home. Gentle handling should bring it around in a few weeks. Just be patient.
As far as feeding frozen, heck, I'd give it a shot. Get tongs and wiggle a defrosted mouse and take advantage of that strike! It's alot easier to keep a freezer of frozen mice. Economical, too, which you must know by buying crickets in bulk.
Have you had the baby sexed yet? And for the curious (me) could you give a ball park figure for the price?
Good luck, and post LOTS of pictures.!!!
