Rocker Cover Leak

Need some help on what part/seal I need to stop oil leak from my B18B rocker cover.

There's oil drip from the cam shaft plug and also around the edge of rocker cover, see pictures below.

Q, what is the seal part called that I need from Honda?

was thinking to replace spark plug O Ring at the same time, is there anything else I might as well replace when at it?
