There is a tool that was built specifically to straighten bent steel crankarms. I have one that was made pre-war by Elgin. They are straightened fairly easily with that tool while on the bike.
For the cotter pin I would apply some Kroil (
Penetrating-Lubricating Oils) to the pin and give it a day or so. Then I would try it again, only repositioning the press as best I could to apply the force so as to push the bend back in the other direction; IOW a little off to one side.
