I created some documentation for our techs for using the Ghost console in our environment. While this is very specific for our environment, hardware, and technical processes, it may give you some tidbits that you can use. I hesitate to post this and make it publically available, as I don't have time at the moment to answer detailed questions about it, and it does give some technical information that I'd prefer not be public knowledge. However, if you could post your e-mail address (in some obfuscated format) I'd be willing e-mail you the web link.
I think there's even a few training videos that we created still up there. The documentation is for Ghost 8, but a lot of it probably still applies. It's definitely not a step-by-step from scratch, but does go over how to set up a task to ghost a machine from the console, at least in our environment.
