The purpose of a Single Point Ground System (or any ground system for
that matter) is to keep lightning transients and charges OUT of the building
and away from equipment so the cables to the aforementioned equipment are
what needs to be connected to the Single Point. Then the potential transient
damage entry point for this equipment is the power coming into the house
which ideally would have its own transient protection. Or unplug them in
event of a thunder storm.
Here on the West Coast we have very little lightning activity compared to
just about everywhere else so you don't need anything elaborate for a minimal
ground system.
The aforementioned equipment meets grounding codes via their 3-pronged
power plugs so I wouldn't necessarily do anything more to them; you might run
into a ground loop by connecting them all together anyway.
