heres something I've cut & paste from the internet. better of taking it to a specialist, that way they can lighten & balance it. most probably re-harden chemically, heat or shot peen.
FLYWHEEL MACHINING Flywheel resurfacing is critical to clutch performance. It is extremely important to restore the proper step dimension when applicable. Unfortunately there is no specification for maximum machining of a flywheel. The amount of material a flywheel is machined can vary anywhere from .005 to .050 of an inch. depending on condition. Removing too much material from the flywheel may cause release problems. As the overall thickness of a flywheel is reduced, the clutch set up geometry is changed. In fact, the clutch assembly is moved further away from the release bearing. Flywheel shims are now available to solve this problem. We DO NOT recommend this procedure because: (A) The starter drive will not engage the ring gear properly, and (B) Use of flywheel shims could encourage installation of a flywheel that is too thin. Lack of structural integrity may cause a "thin" flywheel to explode.

^you only need to machine it once.
cost around $45- $60 to machine, don't know the cost for the extra.
