Answer 1

honestly you should do all of them but mostly edit your draft. 

Answer 2

I am pretty sure it is to ask questions like who, when, where, why, and how. This is because in the prewriting stage your suposes to find out what you want to write about. Everything else is in the revise or edit stage.
