You could get all the updates, you could slipstream/integrate them into
your installation media (network or CD/DVD.)
You could do more than that and use a completely unattended setup method.
And/or you could make images of systems (Ghost/TrueImage/BootItNG come to
mind) and reapply these as needed. You could even go as far as creating a
universal image that would apply to most computers.
Slipstream/Integrate the patches and/or start using some other unattended
method (CD/DVD/Network/Cloning/etc) to do your work for you.
You can download each update manually - based off the KB Article number,
etc. That way you can back it up/burn a CD of them in case you need them
or
use them to keep a slipstream/integrated (updated) Windows XP CD.

You can see the critical (security and other) patches released for a given
month using the following:
http://www.microsoft.com/technet/security/bulletin/ms##-***.mspx
At the end of this line you see "ms##-***.mspx" .. If you simply replace
##
with the two-digit year and the *** with the three character month
abbreviation, you will see the list of "critical" and "important" patches
for that month (since it only happens once a month usually, if you check
by
the second Tuesday (wait until afternoon) of each month - you should be
fine) - note that future months will not work.
As an example...
December 2004's patches..
http://www.microsoft.com/technet/security/bulletin/ms04-dec.mspx
March 2005's patches..
None released.. so that one will fail...
May 2005's patches..
http://www.microsoft.com/technet/security/bulletin/ms05-may.mspx
July 2005's patches..
http://www.microsoft.com/technet/security/bulletin/ms05-jul.mspx
Once you get on the page with each month's list of patches.. You can go to
the related KB articles and grab the appropriate files from there.

Your other choice might be to create a universal image - but I think you
would get more flexibility with an unattended installation.
