Not be able to set up Membership Type and Payment Type
The links to the forms you've provided look like stand-alone CiviCRM Profiles.

To allow for membership registration with online payment, you need to set up a Contribution Page, which allows you to configure payment options and the types of memberships that can be selected, as well as on screen messages and email receipts. You'll include the profile you want completed in the set up as well.

The CiviCRM book explains in full detail how you can set up a Contribution page: http://book.civicrm.org/user/contributions/setup/
