Thanks, and what about the negative 12v? Do I split that somehow across the 3 devices?
Err, negative 12v and ground are not the same thing.
Voltage is a measurement of the difference between ground and the supply point.
If you're thinking of battery powered applications the negative terminal is ground or 0v. Same with the negative terminal from a PSU.
What you'd do is something like this rough diagram
