#1. one word: assembly lines(yes that is one word!) most to all German factories
#2. Simplify the construction of a heavy tank with sloped armor
#3. Build more trucks so the infantry can keep up
#4. Focus on jets and long range bombers!!!
#5. Keep Italy out of the war until Rommel can attack with 3 panzer divisions and a modern equipped Italian army.
#6. No blitzing any British cities
#7. Take Malta and Gibraltar
#8. And one of the most important, don't let Hermann Goring get hold of the German economy.

now Germany has a 60% chance of partially winning
Actually, more like a .06% chance of winning. It was hopeless. Germany's economic power was equal to Britain's not superior, and Russia dwarved her in manpower. The things you mention are too minor to compensate - and any of these innovations will be imitated by the Allies. As another example, taking Gibraltar is one thing, holding it another.
The odds were stacked much more heavily against Germany in WWII than they were in WWI - it's nearly ASB that Germany did that well at all, and if not for the terrible internal divisions in France, it would have been a short war.
