Drive the car
I have a 2002 and while the IMSB does creep into the back of my mind from time to time I drive and enjoy driving the car.
Don't get overly paranoid
Do the do diligence, check your filter, drop the sump from time to time to see what kind of materials your engine is wearing down.
If you need to do the clutch then of course that's a good time to do the IMSB
Like many I'm +100k miles, having put 48k on my self. That is by no means a pass on the IMSB and I think I will do when it is clutch time. Problem or good thing is my clutch is still strong so do not know when it will be time.

AND to really make you lose sleep, there are many more parts that can fail (AOS, WP, Crank Pos sensor, Fuel Pump relay, Coolant tank, Coil packs) and put you out of business
DRIVE the car!!!!!!!!
