Plan for an area where the pup is safe either an xpen or part of a kitchen that you can partition and put the pup there when you are out or moving around doing normal every day stuff. It is very easy for a new Yorkie pup to get underfoot and hurt. You need food, bed, food dishes, toys, and some chews such as the nylabone. I do not recommend greenies or most of the chew toys available in pet stores. DO not use wicker beds as they can splinter with a chewing teething puppy and cause real damage.
The breeder you are buying from should be a dirth of info and also should either give you some food or tell you what brand they are feeding.
Talk to some Vet clinics in your area to find one that is experienced with toy breeds of dogs. You will need someone to do your intial health check on the pup anyway and not a bad idea to have someone in mind should you run into trouble.
You need to keep a new pup away from power cords and just about anything else around the home they can chew or get into. They are babies and don't know the dangers, you have to think for them.
Hope this helps.
