Not totally correct, since power is in linear direct proportionality to torque, torque is very important, you just need to know rpm and gearing to get the entire picture.

Correct, but generally peak power is fairly close to redline, which I assume Munit meant.

More power gives you more wheel torque at any given speed, so why bother with those extraneous calculations?

I think you are forgetting about the third component to acceleration, traction. Not too much an engine design can do here, but linear power delivery certainly helps. Something both engines have.
