A lot of what you're posting is completely normal puppy behavior. Have you ever raised a puppy before? Your dog is not a problem child, but a normal puppy doing normal puppy things. She will grow out of most of these behaviors, but it's going to take months. In the meantime, just accept that puppies have accidents, they want to play and explore everything all the time, they want to be with you all the time because you are their new litter and dogs are bred to be social creatures. She's mouthy because she's teething, and this will also go on for months. There's no need to make your dog afraid of you, and is probably the most counter productive thing you could do.
