Form plugin

I need a plugin for a basic free membership site.
I want to be able to protect some data / pages until users are approved.
I need the users to be able to edit / update their profile information.
I want a form with custom fields and ideally would like to have some other forms available for the user to update certain info.
So once they register can come back and add more info, possibly to a linked form?
I want to be able to layout the form in more than one column.

I am working with simple membership and the form builder addon at the moment.
Is there anything else where I can have multiple columns and link more forms to user.
Access to the database where I can approve members etc.

Any suggestion or ideas please.

Thanks
Mark
