It sounds like you have the basics. Does he have a hide and a place to climb? The 10g tank is pretty small and will be tough to regulate temperature. I would get a temp gun or a digital thermometer with a probe so you can be sure of the temperatures - they're important. He's going to outgrow it quickly so I suggest planning for a larger tank when you can. I'd get at least a 4'x2'x2' enclosure (you can build your own if you don't want to buy one). You can do it all at once or piece by piece as your budget allows. Invest in good lighting in the larger enclosure (it's well worth it in my opinion) and he can move in whenever it's ready to go.
