multiplescripts that need to be run, can this be done in InstaDMG, what is best way

Hi All, I have multiple scripts that need to be run. Including a script that will give the computer a unique name, and then another script that would bind the computer to AD with that unique name. Now can I run these scripts and many more somehow thru InstaDMG, or should these scripts be run thru ARD after? I would prefer running them somehow thru InstaDMG or somehow getting them setup to run as a loginhook, but how would I do that thru InstaDMG as well. Any help would be greatly appreciated. Thanks, Steven Stuart
