Integrate Shipping Info From MarketPress into Membership

I'm having a hard time integrating MarketPress and Membership. Here is what I am trying to do:

I am using MarketPress, and taking advantage of the ability to save shipping details for logged in users. I want to be able to give users the ability to edit their billing info without using the unbranded, default WordPress user area.

So I installed Membership, activated the "Integrated WP Roles" add-on so that the basic membership was linked with the "subscriber" WP role. The idea is to user the "Edit Profile" feature of Membership that allows me to keep my site's theme as the branding.

However, I can't seem to figure out how to get the two functions to communicate. In other words, how can I combine the ability to edit the shipping information from MarketPress with the general functions of Membership using the style of my site's theme?

Also, I will be selling subscriptions in the future, so I want to get this integration right.
