If you can recommend a servo that is better than this one, or is more suited to my needs then please feel free to share.
Without explaining your needs, who can say. That being said, you should be able to make the continous rotation servo rotate in either direction and stop. What is the code you tried to use? Google for "sail servo" for one that can make several turns. Do note that directly powering a servo thru the arduino is probably not the best choise. Best use a seperate power source rated for a couple of amps.
