Hello, fellow Missourian!!! Yorkies Rule!!!
Lots of books on the subject - I liked Yorkies for Dummies (and Housetraining for Dummies). I have a few other books on Yorkies - but after these two - they just repeat themselves.
I keep Bailey in a puppy cut so I don't have to brush her (yay!) - not to mention, she's just adorable in the cut!! She was potty trained in two months and reliable in 4 mos. She doesn't bark and she's a cuddler!!!
Good luck!!
PS - I vote Yorkie!!
