One of my favourite utilities for TFS is a little program called Fissum. Developed by Michel Perfetti, Fissum sits in the system tray and provides quick, convenient access to your work items without the need to startup VSTS or the TFS Explorer everytime you want to create and check your work items.

Michel has released a new version of Fissum which is well worth the download. Get it now from Codeplex.
