Practice, practice, and more practice. Maybe you could entice her with small bits of a soft treat as you are walking. I used to go to the end of the leash and bribe them to come to me and then walk again to the end of the leash and repeat. When they are that young, you don't want to walk them too far anyway.
When and if she gets to the biting stage, it is important to redirect her. Give her a toy to chew on or I used to say "ouch" real loud and it would deter both of mine. If they got out of hand, I gave them time outs. Starting with 1/2 minute.
I am glad that you are starting early. Sounds like you have a lot of good ideas. If you have any questions, this is the place to ask.
