If you haven't installed Eclipse yet, I'd recommend Motorola's MotoDev Studio. It does a lot of the annoying little tasks like set up your Android environment along with your paths, and adds a lot of nice built in functionality to Eclipse.
Even if you've already installed Eclipse, you can add it as a plugin (I haven't tried that myself). It is by Motorola, so they have some Motorola centric functionality as well, such as the ability to add your app to the Motorola market. Anyway if you're interested, give it a shot: http://developer.motorola.com/docstools/motodevstudio/
