Great choice of skis, for a beginner or anyone else! Now complete the good job by getting the Rossi Axial bindings, and that will extend your warranty for a year - not to mention that they're great bindings. When it comes to safety, we all need the best bindings. See what your DIN would be, and get the Rossi Axial bindings on which your DIN falls closest to the middle of the DIN range. The DIN is the correct tension setting at which you will be best served - released when you should be, held into the binding when you should be. Let us know how you make out!
Next great idea, and it's worth more than all the equipment advice in the world: Take lessons. A series - a SERIES - of lessons, and be sure that at least a few of them, if not most or all of them, are private lessons. Then you'll have the best equipment and the best beginning.
One more thing as far as equipment goes: The most important equipment you'll ever own are your BOOTS. Custom foot beds and a professional boot fitter are musts. Without proper boot fit, the other stuff will be worthless. The boots link you to the bindings, and the bindings link the boots to the skis. Any modern bindings will perform that linking function well, but boots are trickier and more individual.
