Wow! What a trip down memory lane. I've not seen most of that stuff in years.
The tank, being that it is smaller, should clean up, and once sealed, be fine. I don't recommend the warm water trick to try to reseal the tank. The aquarium cement used that long ago was a tar like product. Over the years it tends to dry out and get hard and brittle. Way back when the warm water trick worked, because it would soften the aquarium cement a little and let the glass reseat in it. Today, it's all hard and it will no longer do that. Best to seal the inside seams with silicone.
As for the light, note that it is metal, and is not grounded, and so on. I recommend that if you plan to use it, that you replace all the electrical stuff with a retrofit kit of one sort or another, and make sure it's properly grounded on a GFI circuit.
The heater I wouldn't trust. If you think heaters are bad today, the ones way back then were often far worse.
The booklets are a real find. They come from a time when TFH was really trying to produce good books, and the information in them is mostly still valid. If you happen to have any of them about mollies, swordtails, or guppies read them and weep for all those varieties that looks really fantastic and are no longer available today.
