You might want to check out www.deerfernfarms.com for the care sheet listed there. There's tons of good, valuable information on everything from feeding to housing to heating. Chances are your little one is too young to sex at this age - maybe an expert could tell, but we probably can't tell you here.
Please note also that heat is not everything. Proper temperature gradients are critical, but light (type and quality) are just as critical to your uro's health and well-being. For example, if your critter doesn't get appropriate UVB exposure, he will not be able to properly absorb the calcium from his diet, leading to severe health problems and eventual death.
Research is the key - read a few good care sheets (there's some here on the Kingsnake site, too!). If you have more questions after that, please feel free to ask. There's lots of good, helpful, knowledgable folk around here!
Congrats on your new uro!
