Since you are looking far afield in the rebuild, I would like to suggest a couple of other things to 'get out of the way:'
- spark plugs - they don't last forever
- air filter - toss the old, put in a new
- cabin air filter behind the glove compartment - they can pick up all sorts of funky stuff
- lubricate the hydrocarbon converter linkages - use a high temperature grease
- check belt - they almost last forever
- change radiator coolant - you'll get the inverter coolant anyway but radiator now is a good start
- consider 88C thermostat - I got some from Japan in January, at cost $20+shipping
- buff out haze over headlights - easy to do now
- measure all tread depth for all four tires - looking for abnormal wear pattern, can help on 4-wheel alignment
- 12V DC battery - they don't last forever and there are alternatives
- throttle plate cleaning - no so convienced about mass air flow cleaning but inspection is good
- PVC valve - what the heck, easy enough
