Yes. Take them autocross and to some track days HPDE, show them the right places to drive cars at the limit, no late night drag races on the street or through the hills.
Those modifications are certainly fine but the biggest benefit will come from Brake pads and fluid, getting a good alignment with lots of camber up front and tires (just better rubber in OEM size or very near it, bigger faster tires are overkill for the amount of power this car has). The OEM springs and dampers are very very good, most drivers would not perform significantly better with even the very best coilover setup underneath them (whatever that may be) imo you don't need to lower it and stiffen it and compromise daily driving. But it's still fun to do anyway.
If your son has the attention span and drive he'll probably have read half this forum by Christmas and will be bugging you for a supercharger, good luck and have fun!
Edit, not sure what Texas is like for emissions laws but a header and tune is a noticeable boost in power, or so I am told.
