Any gas tube or solid state protection at both ends is all that is required. If you are using only one pair, just get a one pair protector and tie all the other pairs together and ground them.

The most important thing you can do to insure safety is to provide a rock-solid ground. Even an old carbon protector will dissipate a fair amount of energy if you have a proper ground. Use the same gas tube or solid state protectors on both ends to keep it simple.
