Answer 1

form.is_valid() runs through your form's (and model's in case of a ModelForm) clean method's, returning True or False

If you plan on changing form data you can do it within the general clean method or at field level, e.g.

class YourForm(DerivingClass):
    # regular stuff

    def clean_(self):
        # here
        return self.cleaned_data

    def clean(self):
        # or here
        return super(YourForm, self).clean()
