987 Rear Main Oil Seal Replacement - What else should I replace?

Newbie to the forum here,
I have had my 987 Boxster for a few months and have been aware that the rear main oil seal is leaking slightly.
I am going to replace this and the clutch whilst I'm there, but I am wondering if there are any other preventative parts I should change whilst the gearbox is out?
 
The dual mass flywheel may need replacing. There is a rotation test to check for wear. Mine failed this test on my 987S Gen 1 Cayman at 58K miles though I can't recall the test measurement. The IMS cover seal can also leak. My clutch release bearing disintegrated on removal and I also had to change the guide tube that it slides on as it was badly worn. There is a factory tool for inserting the new RMS which my OPC lent me.

The exhaust flange studs will need replacement if they haven't been done.
