I think that what you describe are temperment traits that are seperate from giftedness. Although, being gifted might amplify the traits.
In the book Raising Your Spirited Child Rev Ed: A Guide for Parents Whose Child Is More Intense, Sensitive, Perceptive, Persistent, and Energetic by Mary Sheedy Kurcinka, DR. Kurcinka addresses your very questions. I recommend this book to everyone, even if they don't think they have a "spirited child".
I hope this helps and am sorry my response is so sparse, I'm seem to be running on half a tank, today.
