Answer 1

This could be done in your theme, or a layer override plugin. (Look up Advanced Themes or Layer Plugins in the docs.) Override the form_fields() function, something like this:

public function form_fields($form, $columns)
{
    if ($this->template == 'ask' && isset($form['fields']['content'])) {
        unset($form['fields']['content']);
    }

    parent::form_fields($form, $columns);
}
