don't forget something to control the heat pad. they can get hot enough to burn your snake. you have the option of buying a thermostat (proper) or a dimmer switch (not as good but much better than nothing). you will also need something to check temps and humidity.
on the bright side ( no pun intended ) you will be able to get rid of the heat lamp. they will only dry out your enclosure making it next to impossible to retain enough humidity.
congratulations on the new ball. their very easy to keep once you understand what their requirements are.
