Unfortunately, I did not find anything good in my location in SharePoint to manage or track user rights. You always have the opportunity to customize. However, there are third-party tools. The best tool I have found for easy SharePoint management is Universal SharePoint Manager v2007.
There are several stellar tools for security analysis and permission information in this app.
