When limits.conf is modified does the system require a reboot?

If so is there another file that provides configuration similar to the limits.conf that can go into effect without a reboot or even user log off?

No, You don't need to reboot Your machine.
You just need your users to log off, and log in again.
In other words, if You chande limits.conf, all new sessions will have new limits applied.
