ProKit 6.0.1 and 7.0

I did a re-install of Final Cut Studio 3 (FCP7). Afterwords I did a Software Update check and found ProApplicationsUpdate 2010-002. Looking on the Apple Support/Download page I also saw that there were these two updates also. After installing the ProApplications Update I checked Software Update again - it said my Software was up-to-date. What about these updates??
