Advice would be to not get Shiros because they're wide and not get an AT binding because you shouldn't be going out of bounds as a beginner/intermediate skier.
Get something more in tune with your skill level. I'd say maybe a 179cm Volkl Bridge and a Marker Griffon. You'll save money and you'll progress a lot faster.
