I can vouch for the previous poster's recommendations to keep toe as close to zero as possible. Too much toe-in makes the car feel nervous and darty, too much toe-out makes the steering "dead" feeling. You can check the toe with a tape measure in your driveway. Even if you get the car aligned, I would check the toe setting after to make sure its as you wish. Some alignment shops won't take the time to get it just right.

Also, make sure you have the steering box correctly adjusted.

If you go toward the high side of the caster adjustment, the car will track better as the wheels will tend to want to stay pointed straight ahead.
