I think you're asking if it's safe to stop, unmount everything, shutdown
the machine, and then start where you left off? Yes, it is. That's
basically what we all do when we reboot for the first time and the
kernel can't find /dev/root.

Within the chroot, just type `exit` to escape the chroot. Then `cd` to
the root of the boot CD and `umount` everything in the opposite order. So,

  umount /mnt/gentoo/proc
  umount /mnt/gentoo/dev
  umount /mnt/gentoo/boot
  umount /mnt/gentoo

and any other partitions you have. Then shut it down.

The next day, boot to the CD, mount everything again, and then chroot in.
