He absolutely looks ALL Yorkie to me, and a cutie at that! His ears might come up if all that hair is removed and then they might not but he wouldn't be the only 100% Yorkie to have droopy ears. I would get them cut to match the rest.
I think in time he'll be a perfect boy. If he is too hyper for you I would invest a litle time in toys that intrest him and some time wearing him out yourself. A bored puppy is a busy one but if you take the time to wear him out some he will be a little calmer.
If all else fails...send him here we'll love him! LOL
