Sounds like you're off to a good start. Just be prepared to get a larger cage soon. They grow fast. I prefer bugs over rodents for the little guys. Once it gets some size you may want to offer larger items which should be okay provided you give them variety, and don't over do it. For my larger monitors I feed large roaches (hissers, dubia, and similar sized roaches), earthworms, fish, eggs, birds, and mice.
