For the form helper - if you have $form->create('YourModel'); then the
form helper will automatically use the "YourModel" model for the
form. However, you can also create each form item with $form-
>input('OtherModel.somefield') to use any other model.
The data that prepopulates these fields is taken from $this->data in
your controller. So if you populate $this->data['YourModel'] and
$this->data['OtherModel'] in the controller (through reading the
appropriate rows, or a requestAction) then your form can prepopulate.
And as Chris mentioned, if you are going to use a form on multiple
screens it makes sense to use an element.
