First off, how much experience do you have?
If you don't have a bunch of experience autocrossing, it will not make a difference at all. In fact it may teach you more than you expected!
The whole idea of autocross is to get you to drive what you have at the limits of control, and find those limits. I always suggest that if you cant say what you want the car to do, you shouldn't change anything. Once you know can identify the weakness of the car and not your weakness, then it is time to make the change. Spend your cash on learning to drive and not on the parts. Once you start the spending, you start going down the slippery slope of no return (and for usually a very small incrimental difference in speed or time).
And the mantra is "It is more fun to drive a slow car fast than a fast car slow".
