app/design/frontend/base/default/template/customer/account/navigation.phtml

app/design/frontend/enterprise/YOURSITE/template/customer/account/navigation.phtml
Open the file and fine this line, it should be around line 34:
Right below it add this:
Just remove any of the links here that you DO want to appear.
