Chris Garrett (a high profile blogger) was interviewed on how he has developed several membership sites using WordPress.
The whole interview is available for free.
I figured you would like to listen 
Enjoy!

I just found these WordPress videos and thought you might find them useful.
They show how to quickly create a membership site using WordPress.

Enjoy!
