I forget about question one at the moment... (sorry.) Question 2: You want to activate the 'Production Frame.' When you are in the camera view that your rendering from, Go to the 'View' menu and choose: 'Show Production Frame.' You will see a double square appear in your camera view which represents the area you will be rendering. (It's a double square because the outside is the 'Full Raster' of your rendering, while the inner square is the 'Safe Area' for televisions.) Hope this helps! :D
