There are many threads for specific cars. They can act as a general guideline...
A.) Sorry, it's a fact of life, with braking and acceleration both heavily dependent on the front tires, and with 60% or more of the weight of the car on the front axles, tire wear will always be worse for the front tires on an FF. A different tire grade would not be a bad idea, but putting harder tires in front will tend to exacerbate understeer. I usually just adapt my driving style to the tire wear problem.
B.) This is easy, by stiffening the rear sway-bar and springs, the car will tend to neutral-steer or oversteer when you lift the throttle midcorner. Under power, though, an FF will usually understeer, and the more powerful the car, the worse it is. Some other quick fixes include increasing front camber/decreasing rear camber, adjusting front/rear spring rates, adjusting the "rake" of the car (front-rear height difference).
We're having a debate in this thread about the applicability of real-world tunes in regard to spring rates for understeering/oversteering cars, read that, too:

As for driving FF cars...
Generally, you brake later and take turns sharper and at lower speeds than FR cars. An FF car will have trouble with constant radius turns that FR cars can take at speeds, best to make them point-to-point, or you're going to be going around that curve for a looong time, understeering all the way, and killing your front tires in the process. Snap oversteer is your friend, as it gets the nose around quickly, just dab the brakes and turn in late, the car will point in the direction you want to go, and you can hit the throttle on the way out.
You have to be delicate with throttle application, and try not to lose too much speed, as you won't be able to pull out of the hole as quickly as an FR car.
Some advantages in driving an FF is that they're stable and usually easy to catch before a spin. They're often also small and nimble and work well on small courses. You'll never be as fast as a comparable FR in an FF car, but it'll be fun driving once you get used to it. Just remember:
in an FF car, you can turn quickly and accelerate quickly, but you can't do both at the same time.
