I'll skim back through my list to see if I've planned to replace anything you're not covering and vice versa.
For what it's worth, Lance328 used to recommend replacing the valve stem seals with viton units while the heads were apart. They're still available on eBay here:

Okay, here are some things I've done or will do while things were apart:
Inspect and replace coolant hoses as needed
Replace all coolant hose o-rings
Inspect and repair the wiring harness as needed
Rebuild the starter (the kit's only $10-15)
Replace the stator (or set yourself up for future replacements with an adapter plate so you can do so by removing the outer cover)
Install a new thermostat (there's a compatible automotive thermostat but I didn't keep my notes on which so you'll have to search the forums)
Adjust the coil pickup gap
Drill the clutch basket to reduce the chance of coffee grinder noise
Replace the water pump mechanical seal
If you're splitting the case, check the oil pump chain
Hope that helps.
