wheels need balancing, sometimes shake is only evident at high speed
Yes it will.
No,but tires out of balance will cause this. Have them balanced and rotated.
Warped rotors is the most common cause.

Bad tires and bad alignment can cause the car to shake at certain speeds.
balance front tires
You probably need to get your tires balanced. Or replaced. If the bias goes (steel belt breaks or shifts), the car will waddle at low speeds, and the steering wheel will shake at high speeds.
yes
Check the idle, crankshaft and camshaft sensors.
Check the wheel balance
Probably in need of a complete tune up.
