1.8 vvti insignia bought

Hi I finally took the leap and bought the 09 1.8 insignia .I asked the dealer about the car and was told the timing belt pump and a new clutch was fitted (clutch fitted less than a year ago by a independent mechanic).he said the flywheel was also fitted.do these need the flywheel done when changing the clutch and are these a dual mass flywheel (please God I hope not).
