The editor will reload the module every time a PyActor, PyPawn or PythonComponent is instantiated. Importing assets into a project is done using the import_asset_tasks() function which is a member of the unreal.AssetTools class.

The uobject.get_world() function returns a uobject representing the world (the C++ UWorld class). Remember that for components, the self.uobject field point to the component itself, not the actor. Thanks to Unreal Engine reflection system we do not need to implement a python class for each unreal engine class, but for performance reason we expose the most common methods.
