I am pretty sure if i searched the forum long enough i could find all the answers to my questions! But whats the fun in that?

i love to chat! lol....
I have lots of questions!!
How would you describe the general personality of a Yorkie?? ( i know personalities vary especially with the way they are raised - i know chihuahuas mostly are timid, yappy and sometimes mean)
I have also noticed the coat colors are different, and sometimes the black fades to blue... Is there absolutly no way to tell if a pupper is going to keep their black?
What are the major health problems that the breed is prone to? All i seem to read about is Liver shunts...What are some more?
What are, if any, are some of the health clearances breeders have or need to have when searching for a good breeder?
It is very nice to meet you all! I know i probably asked what alot of new people ask! but i still hope some of you answer =) I did read the sticky post about Colors... but i am still wondering if theres a way to tell!
