Take a look at Paid Memberships Pro, which is 100% open source, and available in the WordPress repository: http://wordpress.org/extend/plugins/paid-memberships-pro/

Here is some code to use hooks in the plugin to add fields to checkout page. It takes a bit of php skill and programming: https://gist.github.com/1389944
