Welcome to diving, Jay!
First, slow down. Talk to folks. Do your home work. I have been in diving for about 40 years. In that time I have completely reconfigured my equipment about three times. Since, you are just getting started the only piece of advise that I would give you at this moment it to make sure that everything you buy fits you perfect - it completely comfortable and is easy to understand. If something makes you fuss on the surface - it will be a nightmare underwater and ruin your diving experience. Go slow - ask questions -
Once again, welcome!
