leave the snake alone right now, they don't like to be bothered during shed.....
as for your heating, forget the lights for heat, i used to use them and it never got hot enough and they majorly suck the humidity out of the tank.....either get flexwatt heat tape or a UTH (under tank heater) which will have to be controlled by a thermostat (Ranco, Johnson, Helix, etc.)....and u said u have A hide...u must have 2 hides, one on each side of the tank....
