Under "Care Info" check out the Gray Tree Frog section. It has everything you need to know about keeping a gray. It isnt recommended to feed any wild caught insects to a frog in captivity due to several reasons, pesticides mainly. It would be best to purchase your feeders at a local pet store, a petco or petsmart, online or raise them yourself! I would purchase a light, one that simulates daylight, they are usually blue in color. A 40 or 60 watt bulb would be alright I would think. Then set it on a timer to be on for about 10-12 hrs. They give off some heat too so with the seasons changing that would be good, otherwise the frog may try to hibernate if it gets too cool. Mist the terrarium daily, have a shallow water dish for it to soak in and never use tap water unless it has been treated with a dechlorinator. Spring water is good - it would also be wise to get a temp and humidity gauge. And always keep the hands off rule with the students!
