You should be able to download them from Microsoft.com. Just do a search for updates and then follow the instructions. IRRC SP2 can take some time to download
Sorry, bit late, I don't get to spend much time on here to read the posts, let alone reply!
I would be happy to post you SP2 (the only one you need, as posted above), PM me if interested, not a problem.
I would also recommend taking a look at Autopatcher, which is a free download that includes SP2 and ALL the hotifixes etc, so that you can choose what to install right from the single file, very handy! If you don't have a broadband connection I can download and send you that.
