Start off with a base that you want everything attached to then join components to that base, if you want sub-parts then add more bases to that main base.
To link the objects - under the properties tab of an object you should find a vehicle property. Set the vehicle of an object to another object that you want it to follow, in this case as I described above you would set the vehicle of each component to the base.
But you would still have to copy them individually.
