Sounds like a typical little Yorkie. Mine (a male), however, has become much more settled as he has gotten older. I couldn't even comb him when he was a pup - such a wiggleworm. He is 10 months old now and much better.
When mine is on a leash - he can pull like a husky. It is unreal how strong these little dogs are, isn't it?
I really don't think spaying should make much difference at all -- but, if anything, I would think that it would have a more calming effect than the opposite.
Good luck!
