I had the same problem here and went to the local dog show where I met my Mentor.  She is a Maltese breeder and has handled other breeds as well.  She agreed to mentor me even tho this is the job of the person that you buy your show dog from.  We are now great friends and talk on the phone every day.  She made me agree to very strict rules, most of which are related to sharing w/ others what she has taught me. I have found that she is very willing to help others if they ask her tho.  Once I started showing and getting in the ring, other exhibitors have been very willing to help me with suggestions here and there.  It just takes time, but I suggest get w/ someone that shows a toy dog in your kennel club and learn how to show the dog.  There is lots about coat care on here and there is also a link on my website under Yorkie Info to Jon-An's website and she has lots of good info on grooming, coat care, wrapping, and top knots.   
Good Luck!
