Hi Chris,
perhaps a look at the official documentation on how to provide implementations for extension points, especially the topic on how to setup your python package descriptor so that trac will automatically discover your plugin. See for example http://trac.edgewall.org/wiki/TracDev/PluginDevelopment#Packagingplugins When you package your plugin, and include a proper entry point named trac.plugins to your setup.py, and also deploy your plugin on the python module path, then trac's component loader will automatically load and register your plugin with the required extension points. There is no need to import your module explicitly.
