The way I see it, if i'm hearing tire squeal from the front, it's understeer. if I'm hearing tire squeal from the rear, it's oversteer. Right now, my car is set up such that going into a turn at a good clip will have all 4 tires squealing lightly at the same time.
As you suggested, I'm not exactly keen right now to run out and mess up the balance, and I'm trying to figure out what is causing the understeer.
Here's my alignment setting at the moment:
-3F/-1.2R
0 toe all around
Tire pressures are 32psi all around.
I use this setting for street as well since I take part in track days every 2 weeks.

We're in no shape to diagnose the cause of your understeer on an internet forum. Tire sounds are certainly not a way to diagnose it though, IMO due to how much variation there is between different compounds. Understeer and oversteer conditions themselves are pretty easy to diagnose (I know what you are talking about, just figured I'd clear that up).
Ask others who run the tires what pressures they run at. What are your spring rates and swaybars? In what phase of cornering does the understeer take place? Is it possible you are simply overdriving the car?
