Idera currently offers a free toolset for SharePoint Administrators which fills in many of the gaps in the tools and reports provided out-of-the-the-box by SharePoint 2010.
You can download the free Idera SharePoint Admin Toolset from here: http://www.idera.com/SharePoint/SharePoint-admin-toolset/

The Idera SharePoint admin toolset essentially works by installing itself as a separate Web Site in IIS containing Web Services which then polls the SharePoint Farm for information.
The actual toolset is a client/server application which requires the distribution and installation of an MSI to all necessary SharePoint Administrators.
