Perhaps you should put clothes on him everyday and see if he gets worse. I can't really believe that is the reason he's pottying everywhere. Yorkies get mad and pout if they don't get what they want, but really they aren't like humans and don't hold grudges. Perhaps he is still too young and perhaps you aren't taking him to potty often enough or consistently? Just a thought. They get used to clothes very quickly, but only if you put them on them regularly to start with.

When he starts biting too hard, holler "ouch" loudly and stop playing and ignore him for a couple of minutes. Then try playing again. It's just a puppy thing.
