Did I ask something impossible here?

Hi folks, new guy here. I got started with nLite earlier today, and I seem to have developed what I feel is a stupid question. The thing that makes me wonder the most is what the correct procedure for procuring a list the hotxies and updates to be included with the unattended install disk. The KBXXX references - is there a way to determine exactly which ones a user needs to download? I'm working from a Service Pack 2C disk. Everything is set up except the hotfixes and updates. My current method, as I read it on a few posts here, was to install the OS and upon the first Windows Update session, grabbing all of the updates to be installed during the initial visit to Windows Update. I went through the list, item at a time, and downloaded them all. Is there another way to do this? Is there a file or website that tells me which ones I need to get without having to check using the Windows Update method I described? I guess I'm looking for a place that would give me a list of all the KB numbers I needed to download. Thanks, I hope that makes sense to everyone. J
