I don’t think I’ve encountered a specifity of _pixies_ being vulnerable to iron, but rather all things that are classified as Fey Folk, and even then just the way that it would make it difficult/impossible for them to use their magic on it.
Depends on the setting. In my experience, vulnerability to iron typically means the touch of it will burn and/or poison them, but you do sometime run into stuff where it simply neutralizes their magic. Or even magic in general. Similarly, most places it’s all Fae Folk that are affected, but, while not stated outright, it seems that in the Need novels, pixies are the only species harmed by iron.
