Sorry to hear about your and your dog's injuries. She will probably recover no problem. It's not like a sanguine dog to turn shy because of an attack like this one. Keep socializing her, and don't let the event traumatize you either, as she will respond to that fear. If you're unsure, there is a book floating around that has been absolutely wonderful for me, and has made not only training but understanding my dogs really easy. It's called "Dog Talk" by John Ross, and it teaches the human to train the dog from the canine's point of view and takes the common stumbling blocks out of the way so you can really get down to business.
I like that you aren't automatically slamming the breed, but I'm equally glad the owner is being decent about it. Dogs are, by their very nature aggressive creatures, but humans are by their very nature, jerks. Dogs are very social, of course, but aggression is what those pointy teeth are for. For the most part pit bulls are just like any other dog, except for their tenacity. It's not that their jaws lock, that's a myth, but they do have very powerful jaws (their jaw muscles run all the way to the top of the head) and don't WANT to let go. I can swing my pit bull around in complete circles with a chew rope, then whisper drop it and she lets go.
Anyway, I imagine you were yelling your head off, already, but my pits are very responsive to voice command. Many dogs, even ill-trained ones, will respond to the "voice of authority", but sometimes they won't, unfortunately. Properly trained dogs should respond after one command or be prepared for the consequences. I hate to see people saying "sit, sit, sit, sit, sit..." and not correcting their dogs. Or punishing them for coming when called because they didn't return right away. Contrary to your inclination, you have to treat the "come" response like the best thing the dog ever did, no matter how many times you called.
Anyway, extraneous information aside, I wish you and your friend, Molly a very speedy recovery.
Edit: That took me awhile to pound out, but I'm really impressed, Tostig by your rather impressive grasp of human-canine socio-aggro mechanics.
