The easiest way to tell if you would like the clutch helper spring is to just take out the spring that is there now. You can drive around for a bit without it there to see if you like the way it feels. When you put the new clutch spring in it feels the same way.

As far as the oil cooler if you don't plan on tracking your car you should be fine with the stock oil cooler you have in the car now.

Other little things you could try is to maybe do something with your headlights or to upgrade your sound system. There are plenty DIY threads to re-do your lights or suggestions for audio upgrades.
