What is this lighter area that I can change duration of?
What is it called and what is it for?
That is the in/out points of the timeline. It defines a region that can be looped during edit playback. Enable looping for that. You can also export only the in/out region of the timeline. This might not be too common for composite timelines but more used on the NLE timeline. Here you might render a certain scene/section to show/post for others to view parts of a work in progress.
Norman answered quite well, but I offer a video tour of the interface.
