Well 1, 2, 3, 5 and 6 I can't really argue with although I highly doubt that Germany was planning to leave anything in Russian hands.
4. however I disagree with, just in terms of lost production and manpower alone the treatment of Jews and other minorities in Germany was incredibly stupid. Many of these groups had fought for Germany in WW1 and there is nothing to assume that they would not have done so again in WW2.
