Pacifier,Potty Training, Big Girl Bed Before the New arrival...where Do I Begin?

I have just received news that I will be the mother of a two year old and a newborn...a little bit of a shock, but trying hard to digest it all! My daughter will be two august 14th and the newest addition will be here no later than sept 1st. I have a pacifier, potty training, and a big girl bed to get her adjusted to(since the baby will need her bed)...where do I even begin?? Help please! Thanks A.
