I've just tried the Mylyn Eclipse plug-in and it's really a great plug-in to manage tasks, bugs and so. It's capable to show only files you shoudld be working on, count time you spend on a task and update task note or comment it. I did not try the Bugzilla or Trac connector but the Generic web connector to interact with Sourceforge.
An very good feature would be a better interaction with Sourceforge, but reading bug reports against Mylyn, the blocker is an XMLRPC or a SOAP interface to the Sourceforge bug tracking software. That's why I filed a bug at Sourceforge
