Hi and welcome to YT. You are being very smart and learning all that you can about your new pup-to-be. This will also give you lots of time to learn about all the things that you will need to get...
good food, treats, bed(s), clothes, harnesses, pj's, carrier(s), blankies, etc. lol
Just kidding, you sound like you are on your way to being a very good yorkie mom!
