I personally use TI Acousticore strings on my ABG. They are very flexible and easy to play, sound amazing through an amp, and are too quiet unamplified for all but the mellowest of jams with other musicians. YMMV.
String noise is simply a matter of good technique; you can work on this in your lessons with your teacher. ABG is a different animal than electric so don't expect to sound amazing overnight without practice.
