Rubal has just made an awesome Security drilldown page which lets you drill-down from a Security Role to show you all Tasks in the role. After that you can review all the Operations(Windows/Reports) in a Task.
Check it out at - http://www.gpwindow.com/securityreport.php
This should be helpful when you are planning for security or making security changes.
