Yes.
Yes, so long as your version of
nero is 5.5.7.2 or above.
Because the image is a raw 2352 image rather than the standard iso image that nero is expecting. (Actually, so long as the image is of a cd with a single data track it is possible to load the iso rather than the cue if burn raw data is checked when it is detected by nero as a foreign image format, but it isn't recommended.)
Instructions for using nero to burn a discdump image can be found
