Unless the flywheel is damaged which is highly unlikely, you won't need a new flywheel. And DEFINITELY (per the Jeep Factory Service Manual) don't let the shop turn or resurface the flywheel which at the most should only have any glazing, if present, removed with emory cloth or a mild grade of sandpaper. Which is, again, per the FSM procedure because of a special dome shape the face of the flywheel has which would be removed if it were machined or resurfaced.
By the way, a complete Luk (highly recommended and what the factory installed) clutch kit is only $170 or so from Dial-A-Clutch - Your LuK Clutch Kit Specialist
which includes the clutch disk, pressure plate, throwout bearing, pilot bearing, and pilot shaft.
