Hi Kaysie,
That is a fine set for a Ceratophrys. Are you sure it is an ornata as cranwelli and various hybrids are also readily available.
Depending on what you want to feed it (also depending on the size of the frog) you can feed them live fish (mollies, minnows are good choices avoid goldfish), various sized rodent (not too many as commercial rodent diets are too high in vitamin A and can cause secondary hypoparathyroidism (one of the MBDs), earthworms and some crickets. Adults do well on one large mouse every two weeks to one month.
If everything goes well I will be away for a couple of days looking for some hellbenders so if you other questions I will answer them when I get back.
