There's a back up option under System Settings, I think. It backs up everything on the system--you'll need something like an external HDD to fit everything (it'll probably be a few gigs.) If you restore it on a new system, the PSN games won't come back, so he can delete those first to cut down the back up file size. You have to redownload those (and you can just log in to the PSN on the new one and do that.) No super shitty DRM restrictions on the PSN games, they work like normal, but I think you only get 5 re-downloads.
edit: yeah, like Rman said. I'm not sure about warhawk and the turnaround for a 60gb might be really long...
