Hi Danielle,
Sorry to have to say this, but it sounds like you have a normal puppy there!!
To be honest, with any breed of dog, you have to put a lot of work into training. You may have been told, or you may have already known that Border collies are easily trained. It's true, they do learn things quickly and easily, because they're very intelligent....but because of that intelligence, they need constant mental stimulation, otherwise they get extremely bored and can become destructive.
Puppy training classes are a good idea, and also, when your pup is fully grown, maybe agility or obedience would be good.
With regards to her coat, she is still only a baby, and coats change a lot during that time. As for her hearing and learning abilities, it takes a lot of time and a lot of patience. Do you have a book on puppies & training? If not, I'm sure some of the other members could recommend one.
Also, biting, at that age is completely normal. Give her lots of toys to chew, and if she bites you a sharp 'NO' and then ignoring her for a few minutes should help.
Take care
Lisa
