With regard to monitoring of the ASI I normally ignore it below about 200 feet above ground / water, unless I have deviated from a normal stabilized final approach attitude. If for some reason I allow the A.S. to decay well below normal I will of course glance at it just to assure I have enough speed to flare.
Probably the biggest problem I see in the pilots I give advanced training to is their inability to judge height above the landing surface runway / water. Most of them sort of flare to the landing attitude then just arrive. ( tri. gear ).
The biggest problem these pilots exibit is looking to far ahead down the runway / water, and thus have poor height judgement during the hold off stage of the landing.
Conventional gear airplanes of course require slightly more attention to the landing.
