You may want to think about trying to grow some of the greens so that you can give him a better staple salad since I know it can be hard trying to find good greens in some areas.
As far as the live food goes, at 2 years old he should get 30-50 bugs a week (30ish if you're using mainly supers, 50ish if you're using mostly crickets), split up any way you want. So you can either give him a couple every day or a larger amount twice a week.
