98 Taco 4x4 2.7,manual trans/ maintance

This is the issue, I am approaching 150,000 miles and I have only replaced a starter and battery and front transfer case seal. I have kept up on the maintance on my Taco and I have the money now ,who know if I would have it down the road. I am getting ready to install a clutch kit as a preventative measure and replace the timing set and water pump and thermostat w/gasket. I am also doing the front brakes as well.
Well the question is:
1) Should I have my flywheel resurfaced?( I think I should just so I dont have to do it again in the near future)
2)Any other suggestions as far as the clutch kit?(removal or installation tricks)
3) Any tricks or suggestions on replacing the timing set?
Thanks ahead of time for reading and replying.
