A vent rib is a metal sighting plane attached to the top of the barrel from the receiver to the end of the barrel at the muzzle. They are usually a quarter inch wide and may have small grooves along the top. The venting means that it is raised above the barrel slightly to allow air between the rib and the barrel which helps the barrel to keep cool. "Factory" simply means that it was originally installed at the plant that manufactured it. In trhis case either in Belgium or Japan. Many times aftermarket vent ribs are installed which hurts the value of a gun rather than increase the value. A factory installed vent rib increases the value vs a plain barrel.
It all depends on condition. The 32" vent rib barrel is a rare configuration, even in the Trap gun. If it is in 95% or better condition, it could easily hit $500-$600. sales@countrygunsmith.net

No, it won't carry the required amount of air. A vent is usually 1.5 inch and an exhaust is 4 or 5 inch.
There are several different types of vent hoods which are available. You can definitely get one that will match you kitchen or have it modified in order for it to do so.
The vent rib breaks up the heat waves that rise from a hot barrel which interfere with sighting.
