I'm not aware of one off the top of my head. But Advanced Web Ranking has a pretty cool tool that shows average CTR percentage based on certain factors in organic results. Position one is whatever is in position one whether that's an Ad, a map pack result, or an answer box. Using the tool you can get a pretty good idea of the CTR you should be receiving, depending on how many results appear before the map pack for a certain search.
As far as local ranking after you click through from the map pack, I would imagine creating a similar tool, or performing similar studies would be difficult. You can filter results in the local finder based on rating, price, etc. Plus there is the issue of the results not being the same for each searcher based on their history and location... if anyone knows of such a tool for local results, I'd be interested in it as well... great question!
