Some good advice here (apart from advertising).
However I wonder if you are setting your goals a bit too high here? 15 years away, 130 kg, you want to plane in 3bf (10 knots or less) and sail "most weather conditions".
No answer is right (and can be a potential costly mistake) at this moment. Listen to Joe and try as much gear as you can (longboards, wide shortboards with and without dagger, large rigs, etc).
