Todo app that syncs with Google Tasks and has notification badges? Coming from an iPhone, one of the things I miss the most is the little red notification badges on my app icons. I don't understand why more Android apps don't have them (not even the phone!?). I digress.
Is there an app available that both syncs with Google Tasks and uses a notification badge to keep track of the number of uncompleted tasks?
Try a different home screen manager.  Launcher Pro does this on my phone for email and texts in the app shortcuts in the launcher bar.  I don't use Google Tasks, so I can't speak to that one particularly.
