mv while retaning permissions?

[Senectus .]

I muffed up an upgrade and have decided to reinstall with a better
installation philosophy. (ie /Home on it's own large drive (hda) / on
a 30gig partition (hdb1) and /opt (with games etc ) on a 50 gig
partition (hdb2).).
I want to move my home directory over to the new drive and retain all
the permissions then I gather I need to tell fstab that is where my
home is..
so my questions are:
How do you move and retain permissions.
Apart from the fstab what else do I need to inform of my home drive moving?

Thanks
