Expert opinion here (and I) agree with you, with some exceptions:

Ng4 & f5 look correct, and this maneouvre was "approved" by Kramnik himself.
Kramnik said he's been using this setup with great success vs. Fritz, so he
decided to play it against Junior.

g6 is wrong, but Kh8 is worse. If black plays Rf7, he looks fine. Other moves
like a5, b5 or Bd7 also look reasonable.

Nxd2 was played to enable fxg4. In retrospect if black wants to take on g4 he
may as well play it immediately. White needs then to play Bxe4 and eliminate his
dangerous bishop.

Qe8 was bad, and was played too fast (less than 2 minutes). Other moves should
be considered. e5 is interesting, but probably fails because after fxe5 white
breaks with e4. Kg7 is interesting, and maybe works.
