You can use this tool to automatically install the latest patches for each component. To use, run ServerUpdateInstaller.exe with elevated permissions. I would recommend creating a folder and put ServerUpdateInstaller.exe in there, as it extracts each of the individual patches to the same place as the .exe. The GUI then lists what updates are and aren't installed. Click on the install updates button to install the latest updates. KB968802 (http://support.microsoft.com/kb/968802) has details on how to run via command line.
You can download ServerUpdateInstaller.exe here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=b3b02475-150c-41fa-844a-c10a517040f4
