That thread covers installing crash/camber bolts.
Stock, the front camber is non-adjustable so you have to buy these bolts to have any adjustment.
Factory alignments almost always suck, so adding a bit of adjustability, and gaining a bit of camber will improve turn in. With camber, the tops of the wheels will tilt in just a bit. When you corner left for example, a lot of the weight transfers to the right side of the car. When you have a bit of camber that weight will push the tire flat to the ground maximizing grip. If you have 0 camber, (straight up and down,) it will push on the outside of the tire, which will overwhelm the tire, (less of a contact patch, less grip.) You can go too far for sure, about -2.5 degrees front is the most I would run on a street car.
You're asking them to zero out toe because odds are it's close but not perfect from the factory, so this will minimize wear on your fancy new tires. If you decide you want the car to turn in harder while cornering, you can add a little extra camber, and/or a little bit of toe out, this will cause the front tires to point out a tiny bit. This accelerates tire wear quite a bit, but if your preference is for that hard turn in, replacing tires more frequently becomes a little less bothersome.
When you add a bit of camber, it pulls the tops of the tire in a bit, so it's getting closer to suspension, further away from the fender. If you get -2 degrees of camber front, -1 degree rear, which is a decent place to start, (again, zero out toe,) it will make it look a bit more even because there is tons more room in the rear on these cars for wide wheels/tires than the front, so more camber up front will help aesthetically just a little, (as well as with handling.)
