Trouble with Web Form

I recently intstalled the Converio theme. I am having trouble with the sign up form. I’ve included a screen shot of the site.

There are two problems:

  1. I cannot figure out how to take people to the webform once they click on the sign up button. (I am using MailChimp for the follow up system). Surely there is a way to do this as I do not want the whole form on this page?
  2. There are only 3 fields available in the form (name, phone and email). I need to capture the addresses also.

Can you recommend the best way to achieve this? I have looked through the help center and forums and cannot find anything.
