This one - A Procratinator's Guide on Getting Things Done is worth checking out for methodology (non MBA related, however, but might be a useful read for interns). As for technology I would advise another tool: Backpackit.
I first read about it in theDivineMissN post and use it ever since to make wonderful to do lists. An example of which I've made below in 37 seconds :)
Worth checking out and has a lot more than that even in free version.
