Servos do not require a motor driver as they have one built in if that's what you mean.
If you use the atmega8/168/328 you could use the code given here http://www.societyofrobots.com/robot_50_robot_sharpIR.shtml (http://www.societyofrobots.com/robot_50_robot_sharpIR.shtml) as the $50 robot uses the exact setup you are looking for, two drive servos and one scanner.

Yes.

It may be difficult to connect a servo directly to that, so you may want to look into a Roboduino, Romeo Arduino, or a servo shield for Arduino.
