What's in these files? Do they have conflicting settings for any of the
variables (i.e. if you run both, can you then use both products without
needing to run either script again?)?

If they don't conflict, the best place is probably in /etc/profile.d,
where the settings will be picked up automatically by all users.

It creates the file /var/lock/subsys/local if it doesn't already exist.
It's just a way of recording that the rc.local file has been run.
