Welcome!
I find that people often underestimate Yorkies in every way! They can be all terrier, very athletic, very smart! I have trained Jackson a lot by myself. We share a really strong bond.
I use treats and don't see anything wrong with it, it's worked very great for us. He's not very praise motivated but every dog is different. I do not give him a treat after every trick... they are phased out. He will do 20 tricks for just one little treat if I ask him to.
Welcome to YT and congrats on Toby! He sounds like a gem
