Well, you get a lot of stuff to be sure... but I'm not sure of the quality of some of the items.
For example, I don't trust the case or the light not to be garbage. The screen protector too, for that matter... A light is probably something you want to see a lot of reviews on.
Stuff you probably wouldn't need:
It's a standard USB cable so I have many extras. It's not a cell phone so I can't see myself needing to charge it in a car... I've never used the lanyard before.
I'd go with an m-edge 700 cover for 15.00, a well reviewed light for 10-20... A charger if the USB charging is inadequate for you.
