Nice pets you have their and your little albino is great, I have one just like it. As far as the light goes, with albinos they have real sensitive eyes and I've heard can actually go blind from bright lights. You should get a red heat lamp and a night lamp as well for heating. You could buy a fixture with a dimmer and get a 100w bulb and dim it to fit the amount of heat you need. I imagine a plain light bulb is a little stressful on the eyes and they don't really need UVB. As far as the side of the tank heater goes, it has a big sticky area on it and sticks to the side of the tank perfectly. Just make sure you put it on the opposite side of the tank that the water bowl is on.
If you decide to get a divider for the tank to get another frog, make sure that there is no possible way for them to breach it and make sure they can't see each other. You don't need any stress or frogs choking on each other.

Other than that everything in your tank looks OK to me, just make sure when you feed him that he can't ingest anything in that tank. There has been casualties where they'll accidentally eat a plastic plant/leaf, moss, stuff like that and they end up dying, you don't want that to happen, hehe.
Hope this helps you and also, Welcome to frog forums!
