Hi Derek,

The “Combo" updates contain all incremental updates and will update files that 
could have become corrupted.
A combo update is every previous update in a single update package. You can 
update any 10.6 version to 10.6.8.

Combo updaters will install on the same version as they're applying--no need to 
roll back or do a clean install. 
So if you think you've got a bad  10.6.7 install from a regular update, just 
run the 10.6.7 Combo Updater on that system.

"Delta" updaters can only take you from one version to the next. For example: 
10.6.7 to 10.6.8. 
If somehow the 10.6.7 is missing something it should have, and that something 
isn't changed between 10.6.7 and 10.6.8 it will still be bad after the delta 
update.

I always recommended going to the Apple site and manually downloading the Combo 
system upgrades; the only way to be sure that everything that needs to be in 
place is in place. 

Cheers,
Ronni
