My advice is that you do not let your puppy do ANYTHING now that you do not want her to continue as she gets older. It is easier to stop a habit from starting than to train one out of her. Also, puppies thrive on praise.
As you are potty training her, do not rub her nose in the pee and poop or yell at her when you catch her having an accident. This will make her think you don't like to see her "go" and will complicate things when you do want her to go outside. Instead, when she is using your house to pee in, pick her up, carry her outside to the same spot everytime, put her down and praise her so much that she pees again. Timed feedings also help with potty training.
Wait to take her around other dogs until she is fully vacinated. You do not want to have her catch something like parvo because it is costly to keep her alive after such an illness, but can also change her brain function.
Be prepared to fall in love with your puppy on a daily basis. There is almost nothing better than a kidney bean-nub wagging welcome when I get home! My dog is a perpetual clown and even though he does require at least one run and one dog park excursion per day, I would not trade him for anything!
