A combination of describe-{function,variable,...} (to get the filename)
and locate-library (to get the exact location -- you can also follow the
link in describe-*) tells you this. And no you don't have to restart
after that change you just have to reload (and recompile beforehand if
it was compiled) it.

But that's only a must if you change the file! A more sensible approach
is using customize. With X-c customize-group RET org RET you can browse
through all org settings that are thought to be changed. And don't
forget to set/save in that dialog.
