You have the best books given to you already - they are like our "yorkies bibles." I would order them now - it will answer most of your questions.
Books:
* The Yorkshire Terrier by Gordan and Bennett (Wildweir Owners/breeders)
* The Joy of Breeding YOur Own Show Dog by Ann Seranne (Mayfair owner/breeder)
* The Book of The Yorkshire Terrier by Joan McDonald Brearley (mostly for information on lines and photo examples)
Then I would get the video tapes/CD by Sweetyblue for grooming, handling, etc...
Thanks for letting me know about your web page. It is best to ask than not.
