How else do you handle standard software updates? This one will require a restart of course. That said, delta update is OK, but the combo update can help clear up some of those unreported issues that may be floating around your environment.
However, the BEST setup will heavily depend on your environment. We have our users install software updates, but you could take the .pkg and drag it into Casper Admin (as you asked) and set it up as a manual "Self-service" policy. You could cache it on their computers and then do the same. Set it up automatically as a policy if you like as well with a restart warning.
I'd be happy to give your a step by step on any of these if you need to. Most of it depends on your environment and your companies IT policies. Regardless, it's generally a very simple task.
