If this were a class, you would save those full path values from creating your controls, as member attributes, so that you could reference them again when you want to use the "edit" mode on the control commands to set a value. In your case, you would have to use the "global" keyword to save them to global scope variables.
For following selection, that would require either a ScripJob, or directly through the Maya API callback messages. You would also have to handle the case of ambiguous values when you select 2 or more lights, if they have different values.
