Well the normal way to do this would be to use a yum update with --enablerepo=
set to the appropriate name (there should be one in your repo files, but mine
have been changed so i don't know the exact name). Don't use the -y option,
so you can see what all is going to be upgraded before you start the upgrade.
Sometimes not much is needed for a kernel, but this time there might be a
lot.

I thought you were asking about installing F13. Maybe you just were interested
in cherry picking packages. In which case you don't care about the boot iso
and don't want to install the f13 version of fedora-release. You want to
carefully use enablerepo. You should also be comfortable downgrading packages
and probably doing rescue recover in case there ends up being a more serious
problem.
