Too late now but for the record, keep SP2 in a folder on a data partition. Lock the data partition with something like Folder Guard, for example. Keep copies of all the MS and other security updates in the same folder and back them all up on CD/DVD.
If I was hit this badly I'd use these files to do a wipe of the C: drive and do a clean install of the OS, with latest updates, followed by all applications from the original disks. It doesn't hurt to do that once in a while anyway - it keeps your machine running sweeter and faster.
