Depending on the year of production of your car, here's the order I would do things:

1. Rear shock mounts if your car is among the batch that had that problem.
2. Mid grade ball joints from Cobra Valley.
3. 400 lb springs for the stock Bilsteins (if you can't swing the complete spring/shock package at once).
4. Cobra Valley single adjustable shocks. Easy to adjust by reaching your hand under the car and turning the knob. All 4 can be done in under a minute.
5. Sway bar package. If you want great handling, you gotta get the bars.

Shocks and springs without the sway bars is only half the fix. But your car will feel more solid over bumps. The bars really make turn in much more positive.
I don't track, so you might ask others that have swapped out the shifter how they feel.

Hope that helps.
