>>Thank you for reading this, I appreciate any help you could lend. I just aquired a new White's Tree Frog from a friend (he's moving). I have a question about heating his terrarium. Currently there's a heater pad attached to the side of the terrarium, on the outside of the glass. I am worried that the frog will burn himself should he decide to climb up the glass on the inside of the terrarium where the heating strip is attached. Is this a legitimate concern?

This sounds like something you must decide based on measuring the heat on the glass next to the pad.
The air temperature for a White's frog should be in the 80s during the day and 70s at night. If the heating pad produces a glass surface temp over some point (95, 105, I don't know) that may either discourage the frog from resting there or he will rest there too long and suffer damage.
And even if the pad isn't too hot, you should check the air temperature in the enclosure (away from the pad) to see if it is OK. The frog should be able to roam around the enclosure and not have to hug the glass to keep warm. There should be a gradient: warm next to the pad and cooler furthest away from the pad. Shoot for a range in the 70s to 80s during the day, and cooler at night.
I use a 25-watt bulb in a dome for my frog. It raises the air temps a few degrees into the desired range but doesn't create any true hot spots. And it rests on top of the screen cover so the frog can't get to the bulb. The light is off at night.
