^^Ditto.

Swaybars will do the most to correct body lean for the money spent while doing the least to alter the ride characteristics. They are also easier to install than springs.

Springs will definitely help ultimate handling, but for a relatively cheap and very easy to install remedy that will have a huge effect without killing ride quality get some beefy bars on there.

Good shocks would be my next upgrade (I've had excellent results with Koni reds - I don't like the KYBs. I hear Bilstein are also very good). Again, much easier to install than springs and will make a big difference.

If, once you have the bars and shocks, you find the car has too much nose lift/dive on acceleration/braking or still isn't handling up to what you would like, get springs.

Control arm and leaf spring bushings are also a good upgrade. Body bushings and subframe connectors aren't going to make a huge difference.
