In response to your points...
1) This is one of our major concerns. Apathy is beginning with DS already and I'm sure it's because he can't stand doing things that don't stimulate or challenge him. I think going to 4th grade for a majority of his subjects will help with this. We also worry that if everything always comes so easily for him, how will he learn to work for it, ie. study, really put forth effort, etc.
This happened to my son after K-2 in public school. While I read that gifted kids don't get bored, gifted kids can entertain themselves, gifted kids challenge themselves, etc etc etc....not my son. He can't stand review (unless it's part of a game) and his mind seems to need to be constantly stimulated.
