Oak snake questions

[linton23]

This is Ralph he was discovered in a jeep that had been traded into our dealership. I dont know how long he was inside but he was very docile and easy to catch. I have had him for about 2 days before I decided to feed him. I may have went to small but I feed him 2 pinkys today. He came alive and went very active. I have a couple of questions about him one when I caught him I was bare handed. Should I use gloves to handle him or start bare handed picking him up when I take him out to feed him? A couple of times he has shaken his tail fast enough to make a rattle sound is that normal? Is there anything I need to look out for how often should he be fed? The picture was taken when we first got him home. I have got him some bedding made of aspen a hide cover and there is a heater under one side of the tank and a bowl of water. Should i put his hide over the heater or not? Thanks for any help.
