New springs and shocks will not sort out the lean, if this is your main concern then you need to fit H&R Anti Roll Bars, it removes the severe roll of the 1.9 completely and transforms the car, so on your budget, replace standard springs and fit the H&R ARB.
Springs arrest the up and down movement of the wheel as it goes over bumps, dampers, absorb this shock so the car does not bounce, both working in tandem to keep the wheel in touch with the Tarmac, in creasing rate of Spring and damping just does the job quicker, hence it feels more harsh.
Anti Roll Bars prevent the car from flipping round when going into a bend, by ensuring the rear wheels do not lift. The higher the rate of the ARB the less roll, or tipping you feel when in a bend, and the quicker you will travel through it with all four wheels on the ground.
Handling is a mixture of the two, but the ARB has the greatest handling effect when changing on a road car.
