I feel like since it was we who slipped up, fair game rules say we owe you guys an explanation of what those bells and whistles do (warning: you may find it disappointingly mundane), so I'll come back and post some more in this thread later. By coincidence, however, I was out all day, so had better catch up with anything important first.
Edit: Ok, I think I've answered all the questions about details. But let me add the most important point here.
The interface that you see in that screenshot is not actually used by anyone [1]. Those links are there for legacy reasons. Their principal role at present is to lure YC partners into accidentally fat-fingering things. (Don't worry; that doesn't happen often, and we see it in the logs and correct it.) They don't exist in the YC-partner version of Kevin's new HN markup, so they won't be around much longer.
1. The only exception I can think of is that Trevor occasionally helps out with moderation.
Wouldn't that have the same effect as a voting ring?

Also, the orange name thing had been discussed on HN long before then. More than once, IIRC. (Sorry, I don't have citations—too tired to dig them up.)
Perhaps, but those votes are caught by the ring detector the same as others, and the same penalties are applied.
It may interest you to know that when PG added the orange name thing, he also added a page showing stories submitted by YC founders. That really did have the same effect as a voting ring—which wasn't the intent, so he got rid of it. (This has also been discussed on HN in the past, btw.)
Coincidentally, I posted something else about "delete" a few hours ago: https://news.ycombinator.com/item?id=7975137.
"Kill" makes an item be "[dead]", i.e. hidden from users who don't have the "showdead" setting turned on in their profile. A typical case is killing duplicate posts when they don't have an ongoing discussion. "Blast" is like "kill", but also bans the user. A typical case is banning trolls. "Nuke" is like "blast", but also bans the site. That is for spammers.
Oddly enough, no one asked about the most important by far of all these links, perhaps because it also has the blandest name: "edit". That goes to a page where we can edit an item's title or url, or put some moderation flag on a story.
My 1234th day……
I'm not just speaking for myself here, but for everyone who's done it.
/conjecture
I'm guessing it's the ratio of older user upvotes vs total upvotes.
I built a clone at news.intelmap.com a year or two ago, and I don't have the percentages in my admin console. Perhaps an addition since pg's exit?
Good guess, but no. It's a score generated by the ring detector. It's rather out of date, because the code has changed a lot since that computation was written.
Nice improvement! Much better than the old site! ;-)
EDIT: % after 'delete' on every submission
