How to customize the Membership Details page ?

Generally speaking, I would like to know in which files we find information about a curring membership details page. This page lists 4 zones/tables :
- "Your Membership"
- "Personal details"
- "Invoices"
- "Activities"
and contains "Change", "Edit", "View all" action buttons.
I need to display/hide these tables and to custom their rows/columns.
Thanks in advance, it is strongly needed for my website.
