On the "pottyy training" issue, I second the command when you take her out. It doesn't really matter what it is, consistency is the key. I tell mine to "hurry up" and they will darn near pee on command every time, no matter how little comes out.
Good to hear that you got her in to the vet for her shots and a check-up. Those first shots are important, and as long as you keep the fleas at bay, you'll be a LOT better off! It took me over 2 years to get rid of them in the house that I had in Ca. The previous owners didn't seem to mind them, but I sure did!
