I think you sound like you'll be an amazing yorkie daddy. You are doing your research which is so important. I think most of your questions have been answered at this point? A great place to start for finding a good breeder is YTCA. It sounds like you already know that pet stores are a big no no.
the important factors IMO are:
finding a great breeder and knowing what to expect- you're here working on that
time and patience- sounds like you've got it
money- doesn't seem to be an issue
after that it's all about love, love and more love
BTW, one of my favorite members here is a male college student and he take amazing care of his yorkies. I sounds like you would be the same.
Welcome to YT.
