I'll be honest - if my system had been hit with the infections you named, I would backup my documents, bookmarks, pics, etc., and reformat.
At this time, I am unaware of any malware that can get into the Recovery Partition, but I'm sure you feel the same way I do that it's only a matter of time before they find a way. My HP gave me the option to burn the Recovery Partition to CD or DVD (for me, it took 8 CD's) via Start>All Programs>HP Tools. I would think Vaio would offer something similar, as shown and discussed
here.
Let me know if you've found that option.
