If you are getting a young one like i have i have a large plastic container that he will live in until he is a year old because the yearlings like to feel safe and suclueded he has a heat mat wich sustains a regular temp that sits under half the tank so he has a warm and cool area he has 2 hides to get away from everyone once he has eaten one on the cool side and one on the warm side. a bowl of water on the cool side for him to drink and to swim in , a rock that he loves to sit on and if you have enough room a branch as corns love to climb. Substrate anything that isnt toxic like pine or cedar i personally think that chippings are more attractive in a viv.
Feeding= find out when you get him what day they are fed on and what they eat, If they feed on a sat. and that is the day you are around most and the day that you would want to handle him move the day to a thursday so that you can handle at the weekend. Remember to not handle the day you feed and he would be best left the day after aswell.
Humidity= I have a spray bottle (that parents use to squirt flowers with) that i spray couple of times a week to kep the humidity up This is essentual for shedding
The best book to get is THE CORN SNAKE MANULE By bill and Kathy Love brilliant book full with every thing u need to no
and remember that there are no dumb questions on here every one is great and so helpful ask away?
Good luck and Happy Herping
