Good advice given so far. You definitely want to wait 48 hours after feeding. You may also want to check for waste products in that general time frame before handling. If mine are gotten out before their first elimination after a meal, they'll nearly always "take care of business." Not the worst experience of my life, but not the best thing for carpet or upholstery either!
If you pay attention to your pet, you'll know if s/he is stressed, or shedding, or would rather be left alone at the moment. Most corn snakes seem to enjoy being handled and exploring. I have a big, twisted stick that's a corn snake "playground." It's there for climbing on while out of the vivs, big enough for fun explorations, and small enough that I can hold it, prop it on the couch by me, or take it to another room.
Just like people, different snakes have different personalities. Most corns are pretty active, especially when they're juveniles. Some love to burrow, some would rather climb, some like your hair, some hate it. Have fun with your new friend; just stay aware of when your baby needs down time.
