Parvo is transmitted by sick dogs in their waste. So long as your neighbor's dog is healthy, there is no danger. So long as your neighborhood is not over-run with stray, sick dogs, there is very little danger.
To be honest, many vets now are realizing that there is more danger from isolating puppies too long, so they are not socialized, and thus end up with behavior problems (aggression and fear), than there is of getting Parvo in normal circumstances.
Your yard should be fine (so long as you did not have a parvo infected puppy there in the last 6 months). Healthy, vaccinated, friendly dogs are fine to come over and visit.
Avoid highway rest areas, city streets where there are stray dogs, and if you want to be OCD, keep the puppy on your lap when you visit the vet office, as there is a small chance a sick puppy has been on the waiting room floor.
Having a new puppy is a nerve wracking experience. Been there... I feel for you! Just enjoy your little girl. Chances are excellent that she will not have a health crisis. Of course there are not guarantees in life, but you do what you can without living in constant fear.
How about some pics of your puppy?
