From what I understood you are a bit confused on what is what.

The get_serving_url() takes as a parameter a blob_key and not a blob_info and returns a String, which is a URL for a particular image with some extra goodies that you can add in the end of that URL (=s512-c or =s256).

The ServeHandler that you have in your snippet is an attempt to create a general serving handler for any Blob I would guess, but still is totally broken from many points. I would strongly suggest you to go through the overview, where you can see a fully working example on how to upload and serve files using Google App Engine, to begin with.
