I am pondering reinstalling a CentOS Linux server remotely, by installing CentOS' installer into /boot (GRUB) as per this tutorial: ganesh.me: Install Linux Servers Remotely

I notice that there are two different versions of vmlinuz and initrd.img in the CentOS 6 distribution:

What is each one for?

I think that the /isolinux/ ones are for booting a live CD using ISOLINUX, whereas the pxeboot ones are for booting CentOS from a PXE server. PXE booting is when you obtain the kernel and initrd from another server using a TFTP client built into the network interface. Typically you'll see something like "Network Boot" in the boot list in your BIOS.

"Download the PXE boot initrd.img and vmlinuz files to your /boot."
