And after I'd become confident in my ever-tweaked personal methods. Ah well... Guess I'll go back through my uploads whenever the cataloging itch bites me again.
I'd like to take this chance to say that I don't think you should post the artist's commentary unless it says something interesting that actually adds to the image in some way.
You've been posting a lot of commentary-comments that don't contain useful information, like for example in post #1158571, post #863600, post #1300503, and post #1551624. There's no new or interesting information in those, so I think it would be better to not post them.

And how should timestamps, tools, and tags be handled (all of which I see as pertinent, the foremost when there's a large gap between the original and the Danbooru upload, and the latest are sometimes a commentary in themselves)?
timestamps - If there's some special reason why this matters (like "this was posted the day after <current event related to the image>" or "the information in this image is now outdated, as the artist originally posted it X years ago") then I'd post a comment explaining this. Otherwise I don't think there's reason to post it.
tools - Use Danbooru's tags, such as traditional_media and its subtags.
tags - Tags that are actually used as tags shouldn't be copied, since Danbooru has its own tagging system. If the artist uses tags as a secondary form of commentary like you mentioned (not very common in my experience) then I would copy just the interesting tags onto the end of the description field like this: Tags include: "tag here", "more tags", "blah blah blah"
