It's on the to-do list to add a revamped quick start using Eclipse.
You'll need to download Google Play services from Android's SDK manager, and import the google play services library project from <android-sdk-location>/extras/google/google-play-services/libproject into your workspace. You'll then need to update your app to point to this library project by right clicking the project, selecting properties, going to the Android tab, and adding a library project at the bottom.
That's it for importing the library. From there you should be able to follow the SDK integration piece of the guide, as the code itself is the same.
Thanks,
Eric
