Your 2nd point is right, the first one wrong, the compressed air never goes "back" to the turbo.
Also, the turbo has to deal with way higher temp(exhaust gases) then the compressed air could ever reach.
Usually it's like:
Filter(if there is)->Turbo(rise in temp due compression)->IC->Intake

Now I have to correct you on this one.
Turbine is just that - a turbine. Turbocharger is driven by the kinetic energy of exhaust gases. It does not use the same exhaust gases to feed the engine. It sucks in the same air the normal, mechanically driven supercharger would.
The only scenario where you would use (recirculated) exhaust gases is when you want to lower emissions set by certain standard (e.g.
EGR valve). And this is way too modern technology for WW2.

Another funny thing is the exhaust manifold and the tubing, outside the airplane.
@10K amsl you got what, -35°?
And your flying >600kph.
Now, cooling down the exhaust gases can't really add to the efficiency, or am I wrong?
Any thoughts?

I too think this would be odd. This is the way I understood it (twice as shorter route / intake manifold):
Exhaust valves / TC + fresh air => IC (for TC) => SC > engine intake valves (or manifold if you want).
