I’m order parts to replace the radiator, water pump, thermostat & serpentine belt.

Quick question: is it necessary to replace the serpentine tensioner & idler pulley? (my GX has 130k miles)

At 130k I would replace them regardless of their condition.

Yes, cheap and easy while you're in there. Make sure you do the upper and lower hoses along with new OEM clamps too. Don't forget the fan clutch either.
