What are the best applications for the organization of Android phones such as Motorola Droid?

I'm in college and ADHD organize and use a Samsung i760 in the last two years with mobile operating system with Microsoft Outlook and synchronize with your computer to help you stay organized. I just got the Motorola Droid and am trying to get used to google calendar / tasks etc. However I need alarms / Beepers or reminders to stay on task and I am easily distracted on the internet. Advice or suggestions? As a side issue how do you fight against Internet addiction and stay on task with ADHD?
