No, theres a thread floating around that I'll have to dig around for where people ran various decks against "rough lists" for the N1. There really isn't an official list for the N1 test, only rough guesses.
I believe Core6k got you to about 60-70% of the N1 list. I distinctly remember it being mentioned that Core6k + Extra cards in Core10k + Kanji in Context words got you to about 90% which is pretty good.
I think most people recommend after Core6k, especially if you have the grammar and in your case since you've passed N2, to just start reading. Keep vocab lists if you want, but read and read and pull vocab from real-life things. It's likely since you've passed N2 that you'll know the majority of the core6k vocab.
Well, assuming the tags are correct, there are 560 words at N5, another 500 at N4. There are 2700 words that cover N3 and N2. That leaves about 2300 words that are at the N1 level.
Now, whether this is enough to pass N1 depends on your viewpoint. My opinion is, one is not just studying these vocabulary lists while learning. You're reading manga, books, websites in addition to listening to songs and webcasts not to mention all the television you'll be watching. If you're doing this, I don't think you'll get a benefit from studying 8,000 words of which only a small percent will appear on any particular test.
Of those 8,000 words, many you'll have knowledge at first sight even without studying them just because kanji gives the answer away most of the time (annoying at the times it does not). On top of that, you get context to help further.
In the end, it might be enough to pass the N1, but it won't be enough to excel at the N1.
Is Core 10K a deck of 10,000 cards, or 10,000 words in a number of cards, or 4000 cards/words that build upon the Core 6k deck?
The core10k was a deck that iKnow had been working on but later scrapped. Some people grabbed it before it was completely pulled from the web. I believe it lacks natural audio for the sentences. I recently included the Core10k cards into my deck but I realized there something weird with a alot of the cards and exported an excel sheet. I ran some searches and comparisions on the list and realized that a lot of the words in the deck were simply taking prior words in the Core2k+6k that were hiragana only and making them have kanji now. I stripped these cards out and simply kept the cards which were unique words. This left me with around 1200 cards vs the 4000 it should have added on. It could be I accidently grabbed an older version of the excel too, I don't know.
I've looked around and searched and have been unsuccessful in finding the thread where people ran comparisons between different combinations and proposed JLPT1 lists that existed. Its on this board somewhere though...I'm sure SOMEONE knows what I'm talking about.
I'm going to start doing this soon, but the biggest problem is that premade decks are easier to review with vs inputting it yourself. Also Core's sentences are great because they are small. As an example, I'm reading through 俺妹 right now and mining the book where I run into words I don't know. 「あの堅物の極道ヅラが、アニメ観て喜んでいる光景なんざ考えたくねえ。」 this for example is a bit longer than most Core cards, but it also generates 3 cards for me too. I have cut some cards from sentences down to small phrasal chunks to make reviewing easier, but it loses context as a result (in some cases).
Also depending on what you are reading, you get a lot of colloquial speak patterns in potential sentences. EX: 「誰の仕業か知らねえが、俺を陥れるための罠だったんじゃなからろうな。」
Thirdly, you have translations already provided so you aren't left wondering if your interpretation if correct or missing a nuance. Of course that doesn't mean the premade deck's trans are any better, but the assumption is they are.
The solution I had considered to all this was mining the words from the books and then looking up on ALC for example sentences, but they too have a tendency for absurdly long sentences.
I want to keep my cards bite sized so I can do 200-300 reviews in an hour like I do right now.
I think core10k is pretty decent for N2 and N1. The question is, however, if you will really excel at N1, as Nukemarine said. I agree on this. Glancing through the old JLPT2 読解 of Kanzen Master, I saw many annotations like explaining what 光合成 was in a note below. I did not need this description as I knew this word already. I guess that is a good indication for what jettyke said to be true: you need a LOT of words!!

as far as i know...
"pure" kanji and vocabulary are a small part of the test. studying vocab lists will make you do well in those sections, however, remember that you're taking a test and you need to prepare for the question styles that they give you.
reading is a different beast. reading is more about stringing together ideas and forming thoughts and responses. you can be good at knowing what words mean but that doesn't you're good at knowing what paragraphs mean and what conclusions the author is aiming for.
i think listening is even more different and even if you know how to read words you need to prepare your mind to listen.
