If the borders post WW2 were "a little further East", I suspect you'd just see more Germany, with the German-Polish border at the Versaille border or the point the Soviet forces hit, whichever is further East.
If the border was somehow far enough East for it to be relevant, I do think you'd see Gdansk annexed to Poland, and probably the rest of East Prussia, too. It's hard to imagine Pomerania (very little Polish population), and probably not the bits of Prussia east of the Oder but west of the Versaille border. The Western Allies (bar France) were much less interested in punishing Germany than the Soviet Union was - and as far as France was concerned, the US and UK went out of their way to minimize the damage the French could do. One interesting thing is that this would place much more of "Prussia proper" inside Germany's borders; it would be interesting to see to what extent the Allies try to gut the Prussian nobility (blamed to a large extent for both World Wars), and what they put in place instead.
Border-wise, assuming the existence of two Polands that are both not tiny, I'd imagine that their border would be similar to the East/West German border OTL, though without the wrinkle of Berlin.
I do wonder what would happen to all the Poles expelled from East-of-Curzon territories. OTL, most of the Germans expelled from Eastern Europe ended up in West Germany; I wonder what percent of Poles would be sent West and what percent permitted to remain East.
