AF-C is typically used when you are trying to track moving objects, and most often used when you are shooting in burst modes so that the camera is tracking focus with each frame as the subject is moving.
AF-C can also be used for single frame shooting as you track the object of focus as it moves into your composition to the "right place" for you to fire off the single frame.
AF-S it typically used for relatively static subjects where the AF merely sees the object and locks focus "once" for you to take the shot.
The size of the focus box (adjusted with the wheel) is just that, while shooting AF-S, you're adjusting the size of the area where the camera is targeting focus. Big objects, big box. Small objects, (or more precise focusing on big objects) small focus box. There's more to it than that, but that's a good start.
The Zone and Wide Tracking options are just that, as well. Rather than a single point of focus, the camera will use a zone to look for things to focus upon. The size of the Zone is also adjustable with the wheel, when in Zone mode. Wide Tracking brings up a very large target area in the viewfinder, and the camera is expecting to see something moving from left to right, or right to left, (think train coming into the frame).
The AF-C Custom Settings are usually used in burst mode shooting (but can also be effective in single frame shooting). The custom setting configures the "area" that the camera is looking for objects to appear and move in order to track them with AF. The various configurations of this are explained in the manual, and there is one that you can custom configure.
I have my top "pad button" mapped to Single, Zone, Wide, and my left pad button mapped to the AF-C Custom Settings. It makes it a lot easier and faster than menu diving or even using the Q menu.
