Haha snap! 
The problem with the pump on this car is that it's armoured which means you can't adjust the fuel screw. A ground LDA pin by itself makes a big difference but you really need more fuel. I've botched mine for now to make the throttle arm travel further, but you really need to get the pump off the car and angle grind off the armour to get serious. Lose the cat if it has one. Doubt you need a bigger intercooler, it's the size of a house already.
Before you look into springs, get the suspension bushes front to back replaced, there are a lot of them and they will be worn on a car of this age:
At the rear you have top links, drop links, roll bar bushes, lower rose joint bushes, inner suspension arm bushes, trailing arm buses and trailing arm bracket bushes.
At the front you have drop links, roll bar bushes, suspension arm bushes and lower ball joints.
I took a few weekends out and did the lot, then followed that with a 4 wheel alignment. The difference was shocking! Remember this car has passive rear steering and its cornering is very good indeed!
The car has 283mm brakes already, you can step up to V6 Coupe Brembos but you will need to up the wheel size to 16". A better option might be to look at the various performance/trackday type pads that will fit, 306 GTI-6 pads should do (Ferrodo DS2500 springs to mind).
