+/-20kts if I remember from the planned descent speed. It's shown very nicely on the PFD.

Secondly Airbus has flap extension markers (1) and (2) on the ND. Obviously pilot discretion but a very handy tool to have. I guess 737 has the DECEL point for speed reduction hence flap extension.
Not anymore. Or better initially yes but as soon as it enters a “capture zone” the profile is latched. This means the descent has priority over the speed and it can accelerate up to vmo-5 in order to keep the profile. (This for aircraft with descent profile optimization)
