Welcome to Yorkie Talk. I wrote a blog post about potty training:
Potty Training Small Dogs - Dog Life and Style
Essentials are:
Limiting freedom to a smallish area with the pad (crucial for small puppy)
Praise and reward for when she gets it right
Don't make a fuss for mistakes, but be sure to clean and eliminate the scent that might attract her to return to the spot
Yorkie Haven Rescue sells a sling carrier that is very popular (purchases help pups in need of medical care):
