Yes you do have a Dual-Mass Flywheel. Not quite sure how that'll help you but in whatever way hopefully it does.
As far as clutch kits, if you're an independent worker (working on the car in your backyard) then I'd say dealer. Warranty and all that jazz. If you work for a shop then look up a wholesaler company under the name of SSF, they sell OE stuff cheap, hence wholesale.
