Once you have the CBM, end cones and general frame tooling, does it
really cost that much more to add a metre or two to the length of a module ?

You'll still have the same amount of testing to do, same electronics and
subsystems. Is that where most of the costs are ?
the cost purely a matter of the number of shuttle launches
required to assemble the station ? The lighter the modules, the more you
could launch at a time and the fewer flights you'd need ?

Outfitting, meaning racks. The electronics and subsystems are in
racks, not the module shell.
