Mathematica offers a way to keep the namespaces of your notebooks separate, so that they don't share the same symbols (see heresee here).
Mathematica does have garbage collection, but most of the time you don't have to care about it being completely automatic.
Some dynamic variables can remain in effect even if the kernel is quit, as such variables are owned by the frontend. Be sure to remove all generated dynamic cells (via the menu option Cell > Delete All Ouput) before quitting/restarting the kernel.
