I don't know if you can have a single encrypted device that spans 
multiple physical devices, unless you did the encryption on top of RAID. 
I don't think you can use dm-crypt on top of a LVM VG, but I'd like to 
be wrong.

You can easily access them once you're logged in to GNOME. Click on them 
in the 'Places' menu and a dialog box will appear asking you for the 
passphrase.

 From a terminal, you should be able to do something like

cryptsetup luksOpen /dev/sdb1 mydrive
mount /dev/mapper/mydrive /media/mydrive
umount /media/mydrive
cryptsetup luksClose mydrive
