I think you have the right ideas. Here is my opinion.
Airframe log: start after signoff by FAA guy, include ELT battery installation/expiration.
Engine log: Enter the accessories by serial number and initial oil brand/type/amount and filter p/n. This helps to remind you what to purchase in the future and future owners like to know what you used.
Propeller log: Start upon installation and include torque of bolts. If a subsequent torque check is required or done, log that too.
