I'm not sure if this is permitted, so please forgive me if not! But does anyone have decks that correspond to the 総まとめN1 books? Especially the 文法 and 語彙 books. I'd be very grateful!

I would think it's ok unless you do what I'm doing now with a lot of text books... screen shots of the sentences into anki =p. If you have the book and a good scanner, I think this is a great way to make decks with minimal effort and without careless mistakes. The only problem is that longer sentences get kind of small on a telephone so you have to turn it landscape. Not offering to share my deck and it probably wouldn't be of great use to you anyway since it's a mixture of a ton of resources and not just まとめ or any other one textbook.
