To answer your questions as to whether or not do you need them, I guess this is like insurance, do you need it, personally I always like to have fate on my side, by law you are probably not legally required to have them but as per my post above you should have them.
As for benefits, I am using the Michelin X-ixe/Xice2 and they are LRR/Green and Xl which is giving me a smoother ride and about a 2 mpg improvement in gas.
As for do you need 4 the answer unfortunately is yes, you need 2 for the traction wheels and I do not believe that any installer will install 2 only on a front wheel drive car.
The scientific reason you need 4 is because when you go into a heavy braking or emergency braking cycle 80-90% of the stopping power comes from the front tires thus the rear go into a light weight mode where there is a uneven traction caused and this will then cause your vehicle to counter rotate and the vehicle will spin upwards to 180 degrees.
