There is a full TurboGears example provided in the source distribution. You can browse it online at: http://elixir.ematia.de/trac/browser/elixir/tags/0.3.0/examples/videostore
Other than that, the tests (also included in the source distribution) are usually fairly readable and will provide you with many short examples. You can browse them online at: http://elixir.ematia.de/trac/browser/elixir/tags/0.3.0/tests
And please remember to come back when you have mastered the library and you can add some examples of your own on this page to complement the ones provided.
