In terms of keeping track of my events, I use twoschedule (http://twoschedule.com). It's sort of shameless plug because yes, I created, but I created it because it's how I wanted to organize because it works. I'm way too busy to use any sort of traditional calendaring application—I need to focus on what's important now and what will be important next. Twoschedule does this perfectly and it's done wonders for my organizational sanity.
