Welcome, you've come to a great place to learn.
You say you're getting him from a pet store, but the animal is healthy. Not trying to be rude, but how do you know the animals are healthy? If this is your first snake how can you be sure? I'm not saying it can't or won't be a healthy animal, I'm just trying to warn you that many of those stores do not provide proper husbandry or proper diets to the animals they are trying to sell. They also don't employ qualified reptile keepers and many of the employees are pretty cluless and just there to sell, sell, sell. Most of them don't even keep reptiles. They will sell improper equipment, not tell customers that a thermostat is a MUST, sell the wrong prey items, etc...
In the long run, it could end up costing you a lot more money and discourage a first time keeper. There's a reason there are so many BPs on craigslist and other classifieds, and big box stores are a big part of that.
