Not to worry, it looked likes a care sheet to me. Admittedly I just scanned over it real quickly.

Personally, if I were you, I would go with the marine toad for now. They are cheaper and more adaptable, eating a variety of things including plants and dog food. Try getting a Colorado River toad to do that. Also you mentioned a bit of nostalgic feeling stowards this species. I have those same feelings for the spotted turtle as I used to catch them all the time as a kid. Unfortunately for me, it is illegal to keep spotted turtles in Massachusetts. Lucky for you, its not illegal to keep marine toads in New Jeresy.
