Updating my pre SP1 install disk

So i have found the miracle that is slip streaming and have already gone through the process of adding RAID drivers to a install disk so you dont have to jack with a floppy and F6. That was with a different install CD though. What I would like to do is update my OLD SCHOOL Win XP Pro CD(that is preactivated I might add) with everything I can up to SP2. I assume I can slipstream SP2 onto it using Nlite or a few other methods I have read in the many articles there are on how to do it, but is SP 2 the only thing I can add to it. Can i include all the updates up to SP2 release date as well? Plus I wanna throw in those RAID drivers, but I have a great link for that

If SP2 is the only thing I can do i guess I'll just follow the directions for doing that and then mix the above link into it, but it would be nice to have as much as possible on the disk for a clean install so i dont have to sit through Windows update every time I do a clean install
