After managing my instances, I had a similar sticker shock with data store usage. However, the app stats utility, even though its really built around the old pricing model, was invaluable in telling me what my heavy hitters were in terms of data store ops. I implemented caching for my most important routinely accessed data, and that helped a great deal. Also important was to completely move off less critical data from the data store to external storage. This increased CPU and instance time for me, because I implemented it using URL fetch, but in the end, saved a lot of costs.
