cp- a should work fine.  I have used that several times and no problems
yet.  You can add the -v if you like to see the files scrolling by.

If you have the same partitions on the new drive as the old drive, your
grub.conf and fstab should be fine. 

You will need to install grub on the new drive tho.  I usually do that
from the Gentoo CD myself. 

Hope it all goes well.
