Suggestion:
1) in /etc/yum.conf set keepcache=1
2) every so often copy the contents of /var/cache/yum/updates/packages/ (or if 
your on F9 /var/cache/yum/updates-newkey/packages/) to an external media 
(DVDs/USBHD).
3) when you have to reinstall you can copy the rpms back to the packages/ 
directory and yum will see them and know that it does not have to re download 
them. [it still has to get/extract the headers, but they are small.]

This is also a useful trick when you have several machines to update that are 
running nearly the same install, i.e., by copying packages/ from the first to 
later machines, the later machines only have to download the packages that the 
first machine was not running. :)
