Saving Critical updates

I need to install the critical updates to about 25 workstations, and have only one 56k line to work with. I am wondering if I can download all of the critical updates to a file, burn it to CD, then install them from there. It will take forever on 56k, cause they are Win98 clients, with no updates ever installed. I think the security patches add up to over 10mb.
Any help would be great.
Thanks a lot.
