if i got the 18x18x24 what type of lighting would i use?

i have a bearded dragon so i know all about the uvb lights and such do frogs need just a uvb on top of their screen? or do they need any type of heat pad on the bottom of their tank..ive never use a heat pad before..i know they need humidity thats not a problem and ill get a very nice temp/humid monitor for the tank.

i just wanna know what is the best to put at the bottom..im thinking big flat river stones and live moss..but what kind of moss?

and do you guys reccomend those branches that you get from the pet store that bend everywhere if i sanitize it before i put it in?
orrrr....bamboo rods?
