I've got a handleful of macs (all with unique names) and on occasion it prompt a notice about saying another computer on the network as this name and adds a (2) or (3) to my mac.
How can I set the host name from the command line?

Yes you can :
sudo scutil --set HostName "YourHostName"
sudo scutil --set LocalHostName "YourLocalHostName"
to change the computer name :
sudo scutil --set ComputerName "YourComputerName"
To check if everything is okay : sudo scutil --get HostName
There is a couple ways to go about solving this problem.
The immediate change is to to open up Terminal, and issue the command
sudo scutil --set HostName {your machine name here}
The next thing to do is to
sudo pico /etc/hostconfig
Add the following line, followed by Ctrl+O, and then Ctrl+X
HOSTNAME={your machine name here}
Finally reboot
