Great second step is to get Bill and Kathy Love's book Cornsnakes: The Comprehensive Owner's Guide. Should be available via online book stores or via Bill and Kathy directly via their website. corn-utopia.com
Thrid you want to find a good knowlegeable reptile vet. Don't want to waste time during an emergency looking for one and hoping they are well versed enough to be of help. Snake friendly isn't necesarily enough make sure they actually deal with snakes on a fairly regular basis.
Also read up on the forums, after all there is no such thing as too much knowledge.
Best of luck
