Kimmy,

What is your frog's name?

The photos that are posted at the start of this thread (at the bottom) look very dry to me. Don't let that paper dry out!
Like Heather says, they like to soak down here. When using paper they flatten their bellies on the bottom to soak up water and get re-hydrated.
I would get a real thick layer of paper( towels )in the bottom and dampen it really well ( sopping wet !) with spring water ( bottled water).
Misting is okay as well- 2-3 times a day. Don't spray directly on your frog. Spray with distilled water ( which will not stain the glass of the enclosure)
I would not worry about putting too many crickets in the enclosure at night if there is paper on the bottom.
Extra crickets are better for now while he is little and / or stressed. Make dinner an "easy catch"
Fee him well. The white bottom makes it easy for you to monitor the food intake for now-and to see what has been eaten by the next morning.
Remove the uneaten crickets and replace with more each night. If he is little- he needs to eat every night.
Keep a very shallow saucer in the enclosure filled w/ bottled water (1/2 inch or less) ( change it daily )

Don't touch your frog unless it is absolutely necessary. ( if needed wash and rinse your hands well)
You might cover three sides of the enclosure - the frog would feel safer.
Keep the frog in complete darkeness at night.
Develop a day/night cycle for him.

Don't add another red eyed tree frog into the enclosure for at least 6 weeks- or longer.
