I will have to cut the square edged steel vent cover, where it meets
the ceiling.
I reckon I could cut slightly into the pasterboaed above to hide the
jagged edges and any imperfections ........ but ....... which is the
best method and tool to cut the steel?

Depending on the size, a hacksaw, a jigsaw with a metal cutting blade, a
nibbler or an angle grinder with 3mm metal cutting disk
