autocross setup advice

[carvsdriver at msbx.net (Doug C.)]

So now that I've gotten a few races under my belt, I'm looking to get more competitive at the local autocrosses.  I'd like to get some advice from the experianced racers on the types of setups they use.  Here's what I'm running...

-The car is my '88 16v with a stock 1.8l.
-Bilstein sports with H&R springs
-Stock front lower sway bar
-neuspeed front upper stress bar
-eurosport rear upper stress bar
-battery relocated to rear
-I have 15x7" wheels, with 205/50-15 tires (will be getting new tires for next event - most likely falken azenis)
-I usually run about 40 psi in the front and about 43-44 in the rear.

I was wondering if any of you experianced racers have any suggestions as to what I can do that will make the car handle better, or what kind of setup other people use.  Also, what tires and pressures do others use?  

One thing that does bother me a little is that I get a lot of fender/tire rubbing in hard corners that i'd like to get rid of.  I think the offset of my wheels is ET38.  What is the best way to alleviate this problem?  I'm open to getting a seperate set of auto-x wheels if this is the best solution...

TIA!
