"Froglets up to 2 inches...three week old crickets every one to two days." three week old crickets are 3/8 inch give or take. the same size is suggested for 2 to 4 inch froglets, which can also eat prekilled pinkies and supplemented superworms, which have far less chitin than regular mealworms, though they should not be fed as a staple (variety in any diet is always better). Adults can eat fully grown crickets, which are 1 inch or so.
So when feeding nightcrawlers in "sections" you can cut the piece to be the width of the frogs mouth, not the space between its eyes.
Yes, it is true that a large portion of their wild diet would be vertebrate prey of various types, so insect diets require calcium supplementation on a regular basis. Regular feeding of mice can lead to health problems, and if you use feeder fish, its better to breed your own as feeder red minnows and goldfish present disease risks and their tanks are highly medicated which may harm the frog.
