It's a very hard process in some parts of the country getting safety glasses. JAX is the worst place to try, as they have to SIGN OUT glasses there, don't ask why. Some places it's not as hard, but the quality of the glasses aren't that great. I personally have a set of night time (clear) UVEX glasses, which are top of the line, along with the Amtrak Silver Service Neckstrap. I'm trying to get a pair of the shades, but the only type I've found so far are the crappy ones. As for the keys, I would definitely try to compare keys with someone, the AC on your trip north (WPB-JAX) is a pretty nice guy, and will probably let you compare. As for headend pics at JAX, I would wait until after the fuel truck leaves, he's usually gone by 1600, and the train doesn't pull out til 1615.
