Glad to hear you got the first part sorted :)
I'm not sure I exactly understand your second question.
With HTML forms, the page that is redirected to dictated by the
action attribute on the form element. If the method is "GET", the values in that form will be submitted as part of that URL. For example, if the action="http://mysite.com/contact" and there is an input with the name
email and value
email@example.com, the form would submit to the URL:
With CF7, since it's an AJAX form, the page does not redirect by default, however. Though you can force it to redirect as shown here: http://contactform7.com/redirecting-to-another-url-after-submissions/
That being said, I'm not sure if the submitted params will be intact (probably not) - so it might be better to submit from a normal (non-CF7) form to the page with the CF7 form instead.
Hope that makes sense! :)
