Jammedstab,
I'm not going to comment on the crew actions, but in response to the second paragraph of your last post I have to say that with the Dash 1 to 300, it's common knowledge among its pilots that "if you can see it, you can land on it". By that, I mean that if your landing runway is in view, any combination of flight idle, condition levers max, gear and flap will get you safely (and stable) to your proposed touchdown point without exception.
In over 6000hrs on the Dash, I never had to go around because of being too high/fast. The aeroplane is just so versatile and easy enough to fly to enable a stable approach in many unusual situations.
