Just to add on to some of what was shared above--I think what can work, with a kid like this, is to have as few rules as possible, but the ones you do have be as consistent as possible about it. So, pick the behavior that bothers you the most, that you will be the most motivated to be consistent on, first, and focus on that. I can say that every time I have done that, it hasn't taken more than a few days of total consistency to extingish it. Also, don't say something unless you are going to follow through and physically redirect him if he doesn't comply. I have heard it called Get off your butt parenting. I know how exhausting it is. And I had been a teacher, and was quite smug about my ability to manage a classroom. I didn't expect a one-yr. old to make me question everything!
Also...based on what you have shared here I find it highly unlikely that this is a kid who will "even out". Sometimes gifted kids at older ages may hide their ability to blend in, they may lose their love of learning in a bad educational fit, they may become underachievers, but they don't become ungifted, IMO.
