Welcome, You are gonig to LOVE having a yorkie they are the best :-)
to answer your questions about the food I can tell you NOT to give her anything Nutro or Nutromax, it was recalled and apparently making furbabies very sick and some were even dying, we were giving ours nutromax but as soon as i found out i switched to purina and they LOVE it! don't be surprised if she gets diarhea for a couple of days abruptly changing a dogs food can upset their stomachs so just give her a little time to adjust.
If you do decide to crate train be prepared to lose a few hours of sleep listening to her wimper. I found that if you sleep in an old T shirt for a couple of nights to make it smell like you then put it in her cage, also if you can get an old clock that ticks and put it i her cage wrapped up it sounds like mom's heart beat and will help comfort her.
I just went out and bought a whole bunch of new toy for my babies and the favorite has been a stuffed giraffe from pet smart, he's white and orange. I don't know what is so great about him but the dogs love him and only play with him, none of the other ones i got, we've been through 4 already i just went to pet smart and bought all of the ones they had on the shelf so now i have a life time supply haha!
I give my babies a bath once every 2 weeks unless they get exceptionally stinky, their hair is like human hair so it does get greasy from petting them and what not, i keep their hair really short in the summer and cut it once a month, one month i do it and the next i send them to the groomers. during the winter they go maybe every 2 months and i just keep them brushed.
Hope i helped a little, as you come across more questions please come and ask us there's lots of help available.
