Can I save WIN XP SP2 updates and install them later?

The heading is a bit strange but here is my question:
I wish to format my hard disk and reinstall WIN XP.. I also hve the WIN XP CD (of course, original) and SP2 CD... So, after I install my WIN XP, I will install SP2.. But on my computer, I hve downloaded a lot of updates after SP2.. So, after I reinstall will I have 2 download the updates again.. Can't I save my current updates post-SP2 and install them on my reinstalled XP?
