If you're asking about how to walk on the runway on the way back to the top of the stage, you would walk back the same way you did when you first entered the runway. You can choose to do a spin around in mid-stride before you get back to the top of the runway or you can just keep walking with your back to the crowd/photographers. Unless told otherwise, you may stop at the top center of the runway to look back at the audience one last time before exiting the runway/stage.

Yes. This is mainly the case for runway/fashion models. If you hope to be on the catwalk, you must know how to do a runway walk. Print models and other fields outside of the fashion/runway world do not necessarily need to master the walk since they typically are not on catwalks in shows but knowing how to walk is always an advantage, regardless of what kind of modeling you do.
