Use whatever suits you just so long as it contains a vent.
Yes, some kind of venting terminal is needed at the top of the flue - if you have chimney pots then use a clay insert. Never use metal, it will quickly rust out.
Can I ask, is there a special plaster/Browning/plasterboard you should use for the chimney?
