The actual time in the air would be 5.9 hours (probably longer, since spec sheet range numbers usually are at economy settings, but speed is quoted at 75%). Two fuel stops, however, are going to add 1.5 hours (45 minutes per stop, which is conservative) for a total of 7.3 hours.
A normal lens or normal prime is a lens with a focal length about equal to the diagonal size of the film or sensor format, or that reproduces perspective that generally looks natural to a human observer under normal viewing conditions.
Between 24mm and 50mm there are a handful of prime lenses that many wedding photographers (especially the photojournalist types) love to use. Again keep in mind that depending on your style, you might be much better off with a 24-70mm zoom instead, and you should rent / try out lenses before investing.
