Getting a minature beagle!

Hello everyone, my hubby and I have decided to extend our family and get a puppy! She is a 6 week old minature beagle. We are getting her next Thursday. Any advice on potty training? I am a stay at home mommy and I have the time and patience to train her. I am having WLS on March 24 and hope to have her trained by then. Also, what sorts of vaccines will she need, etc? Thanks and God Bless Angela
