You have written greatly on this task my friend. The steem and TRX integration is one of the best thing that has happened to the steemit platform as there are more rewards for steemit users. This has also brought in more TRX users to the system.

You have also given a complete practical guide as to how you can link your steemit TRX wallet to an external wallet like TronLink. The explanation is quite clear and even a newbies will be able to do this while reading through your post. I wish you the best my friend.
