In 1939 you have had the Anschluß, and all of Czechoslovakia is occupied by Germany. If Hitler stops there/Hitler dies and is replaced by somebody "saner" and Poland is not invaded (and no need for Nazi Soviet pact) you see the borders as of August, 1939 stay the same for the moment. Germany may go ahead and split Czechoslovakia and allow an "independent" Slovakia. In Central/Eastern Europe you will have Hungary, Romania, and Bulgaria in the German orbit for starts. Probably Yugoslavia as well as the coup won't have any impetus. Finland will be closer to Germany unless the UK and France fully support it when the Soviets attack. Poland and the Baltic states will be very nervous about the USSR - will they get cozy with Germany, will they get assurances from the UK/France (and will they trust them). In any case Stalin will be faced with the countries west of him involved in one or another alliance system designed to keep the Russian Bear at bay. Attacking Poland could see his nightmare of UK/France/Germany (and other perhaps) coming to the aid of the Baltics or Poland, no way he will risk it.
You won't see a final solution in a Germany run by Goering or any other "reasonable" Nazi, Jews in the Grossdeutsches Reich will be ghettoized/pauperized, and perhaps expelled in some way and Jews in the Nazi affiliated bloc will also get the short end of the stick, but death camps no. You'll see higher levels of armaments in Europe on all sides than pre-1939 OTL, also the US will build up but nowhere near as much as OTL. While there will eventually be atomic weapons, here the push to do this and spend the money needed will be much less pressing.
The Japanese are not going to get much in the way of credit from the western powers both because the west does not want them to "win" in China, and also because the west will need to be spending money on their needs and in a "peacetime" environment where, unlike an outright war, the people and the legislatures will not give them carte blanche to spend on the military. The war in China is bleeding Japan dry economically, the rate subject to discussion but their ability to continue this on their own resources is going to stop in the not too distant future. How Japan responds to this reality - Yamato damashii doesn't fuel aircraft or make munitions - will dictate whether or not there is a war in the Pacific. In a T/L where there is no war in Europe, and the UK/France/Holland can send lots of forces to SEA/DEI and the US has no threat from the east, Japan going to war against this combination is even more insane than OTL. Will that reality be seen by them??
