3) Once you know how to drive the car with stock suspension and know what the car is/isn't doing on the track/course, then begin making suspension upgrades.

All the parts in the world are useless if the driver isn't aware of how they should be best taken advantage of.

Do NOT cage a street car. Cages are meant for cars that are being driven by a helmeted driver.
^Sage advice from one who runs NASA events on a regular basis. And worth repeating twice.

My suspension "checklist" so far includes:
1) Zeal Function coilovers
2) Progress 24mm rear adjustable swaybar
3) GTSPEC trunk cage
4) Nagisa spherical trailing arm bushings
5) Carbing front 4pt bar
6) Nagisa Auto Gacchiri fender braces

*7) do not forget about the most underestimated piece of equipement that makes the biggest difference - a clutch type limited slip differential.
