This is an overview of what needs to be done, a good primer on using Ghost is at www.radified.com
To do a 'proper' restore you're best bet is to use one of their boot floppies. I use SystemWorks, so it's part of the menu there under the ghost tab. The default floppy is good in most cases, though if you want USB and/or Firewire external drives enabled you'll need to set that explicitly (Firewire is preferred in this case, scan my back posts about the debacles I've had regarding external USB enclosures).
I only do partition dumps of my disks. They will restore to ANY pre-sized partition of the amount of you have in it, or larger (you'd need to run fdisk and format on a new disk first, plus the MBR is not saved and that will have to be restored in some other fashion).
You can also do complete disk dumps. Ghost should be able to restore these to 'factory new' disks as the dump does have partitioning, MBR, FAT, etc. info (you'll be allowed to re-size partitions beforehand). I still recommend a basic fsck and format of the entire disk to be safe.
I hope this helps.
