I’m trying to get a screencast for you, but , what part are you not getting? If you are already getting the camera locations fine then its probably just better to disregard the part about the 3D cursor.
The Dopesheet I was referring to is the timeline, I was mistaken. This is at the bottom of the default view. The keys; if you are setting keys then you probably see them. You want to select them with left click and bring up a menu with right click, select Interpolation --> Constant.
In order of events:
1.) position camera, and light
2.) set key ( press I for insert keyframe)
3.) go down to the timeline and left click on the key to select it.
4.) right click to bring up a menu. select interpolation --> Constant
5.) go to the next frame (right arrow key)
repeat these steps for the 10 shots you want.
Then you have to set the length of the animation Output filename so the animation gets saved after render.
1.) set the frame end to 10
2.) click the folder icon on the output area to select a location and name for the file. I would recommend adding a hyphen to the end of the filename, so the numbers have somewhere to go.
Then you should be able to just render the animation Alt F12.
