What's the best way to create a membership form with ubercart?

Basically, organization members have different dues levels, but there's also a bunch of additional information we need to collect from each member, as well. We want them to be able to edit that information, as needed.

Could we integrate Webform with Ubercart? (fill out a whole bunch of information, and then pay at the bottom?)

Do we have the member "create a product?"

Thanks for any helpful clues!
