Other than the bare you should have done before you got one, no. Here is some bare starter info though.
Remember they are still very much terriers and will give you that terrier attitude.
I just found these on google.

The Yorkshire Terrier seems oblivious of its small size. It is ever eager for adventure and trouble. This little dog is highly energetic, brave, loyal and clever. Affectionate with its master, but sometimes suspicious of strangers. It can be aggressive to strange dogs and small animals. In other words, it has true Terrier heritage. They do best with older, considerate children. Yorkies are easy to train, although they can sometimes be stubborn. The breed is demanding and dependant and needs a lot of human attention. The Yorkie is an excellent watchdog, defending its territory in no uncertain manner. They can get snappish if surprised, frightened or over-teased, but are usually very sweet and loving. They can be difficult to housebreak. These little dogs should not be over-protected, for they may become neurotic. The Yorkie likes to bark, but it can easily be taught not to do so.
