Breeding most types of crickets is a pain. I'd recommend dubia roaches. They don't make noise, smell, or cannibalize. Also, if you purchase a starter colony you should constantly have roaches and nymphs of all sizes to choose from for your frog.

A really good cricket setup involves several large containers that you rotate depending on the age of the crickets. In the container with the adult crickets, you put a moist dish of soil for egg laying. Then you take that out and put it in a container with very small crickets once they start to hatch out. You can find how-to sheets for it on google fairly easily.
