This cutey is a frog butt, but dont count him out he is a fun sweet boy.
When fired up his head looks burnt orange its beautiful, i would be keeping him if he wasnt a male. I do see pores and he is 13g. 
He is Pinstripe Harlequinn White out
Crested geckos need good humidity like 70% and temps ranging from 72-77 degrees. If you house temps are near that then no need for heat bulb. UVB is ot necessary they can be benefical. If you use a uvb get a shade dweller and make sure it does not put off heat you do not want to cook your gecko. 
From 6g-25g you can keep them is a 12x12x18 enclosure then up it to 18x18x24 for the rest of their life.  You also can use shoe box tubs sideways until 20g then up them to a 21 qt tub. 
For bedding i say use paper towels as sometimes these guys dont have more then 2 brain cells and eat the bedding and that can kill them. 
On to enclosure set up fill it with fake plants and decor make it where the crestie can hide in lots of different spots. Once your crestie is 30g and above give them a lay box.
