I think I understand what you're asking. You've got Boot Camp installed, I assume you have the Windows installer already, so you're looking for the Windows drivers for the Mac hardware. In this instance, the disks for the MacBook Pro should be fine to load the Windows drivers. The disks themselves won't have the correct drivers for the Mac OS side of things, as it's designed for a different model, but the Windows side is fairly generic, and from past experience should be ok.
The update you reference above is to enhance stability and security running Boot Camp, not for updating drivers necessarily, although it wouldn't surprise me if they hid one or two driver updates in it.
