I do remember somebody on this forum came up with an alternative to answering the Jewish question, instead of full-blown genocide. Since the nazis couldn't have rised to power without their racial and political agenda, the best they can do is tone it down considerably.
Instead of killing Jews and other "untermensh," they can force them to accept Aryanization or leave the country, kinda like apartheid in South Africa. They can be granted Honorary Aryan status if they denounce the Jewish conspiracy and no longer practice their faith(at least not in public). Scientists, doctors, and other professionals would be spared(in other words, we'll tolerate you if you help us win the war).
I'm sure since many Jews were already culturally assimilated, they would go along with it as long as they were left alone. Many would probably leave for Palestine though, but out of protest/frustration rather than fear.
As far as World War II goes. I can still see it happening, but with a different twist. I can't see Nazi Germany become the juggernaut that it became without the war. Thats how they made their money.
They can prolong the war for a few more years by guiding the wasted manpower of the concentration camps to using the zyklon gas to destroy Soviet crops. The bodies that they used for transporting those to Auschwitz can be used for arms. And if they're going to use POW as slave labor, at least feed them adequaely, you can get more mileage of out it.
Problem with that was, the Hitler IOTL was too much of a gambler and a risk-taker to think all this through and plan for the long term. What brought him to power also lead to his downfall. He'd need his generals(and possibly Goering), help filter his ideas to keep them on top.
As far as Goering running Nazi Germany goes, although he was well-organized and more rational than Hitler was, he wasn't that good of a war strategest and as charismatic, though he could've been more than a "yes man" to awful Adolf.
