First thing I'd do is find yourself a good bucket seat. Something that holds you firm, if you have money left over, then go spend it on suspension.

2 reasons for this.

A bucket seat that hugs you, that you strap yourself into and won't let you move around is going to provide you with an incredible amount of feed back as to what your cars actually doing.

The second reason is that you'll have proper bracing from the seat so you can just sit there and handle the car, you won't need to brace yourself for corners or anything like that and you can focus on driving your car rather than keeping your face from smashing into the window every left turn.

Front shocks, I'd see what condition your ones are now, if they're not blown, leave them in.
Springs are important so get yourself something around 6kg at the front and 4.5kg at the rear, you can go softer if you like or harder, depends on you. I've found 6kg front lets you shift the weight of the car forward and back pretty easily and the nose doesn't dip immensely under braking, but it does enough so you can load up the brakes properly. With softer springs you'll get more body roll but this can be countered with thicker sway bars.

Dial up the castor to max and get some xt130 LCA's from the wreckers to get yourself some negative camber instead of the standard positive camber. You'll get much better steering feedback and more grip when turning.
