Replacing the IMS bearing on a '98 is not really necessary. There's a 99% chance it will not fail.
Stay away from lightweight flywheels unless you plan to have the crank/flywheel balanced. The 986 does not have a harmonic balancer. Crank balance is achieved with the dual mass flywheel, so installing a lightweight flywheel could result in vibrations and even broken crankshafts.
