Q1. Can somebody please verify the prevailing understanding/interpratation and assist clarify and fill the gaps (marked by ?)

Q2. Is there a easy standalone program/library in to do the identical? I’ve seen few parsers (although have not used) however they require the whole blockchain .dat recordsdata that i can not afford to obtain for this job.

The block is: https://www.blockchain.com/btc/block/485300
