There's no harm in asking questions. 
Normal room temperature should be fine for your frog. Just make sure you don't have the tank next to a window where direct sunlight could cook your frog
The humidity in the tank should be fine. As long as the tank has plenty of water in it you won't have to worry about that.
As for crickets drowning, well that can be a problem. The best thing to do is to drop them in one at a time when your frog is hungry so it can eat them before they drown. Better to have one drown than a whole dozen dropped in when the frog isn't hungry.
You could make a pretty cool paludarium for the frog. They will spend time on land hidden in plants. So something for it to hide among would be nice. You can also add floating water plants for it to rest in as well such as hornwort and anacharis.
