Unfortunately, the stack exchange system is really designed for a rather specific question and answer format. This format doesn't really fit well with asking for more general advice like this. I expect this question will probably be closed and/or moved to meta as soon as a moderator sees it.
In spite of the above, I do have a few comments. The Anki author strongly recommends that you populate your deck with cards from study material that you encounter yourself, such as your textbook or a story that you're attempting to read. This is the way I've used anki for the last 5 years or so. With that said, he's also provided a means of sharing decks, and some of them have proven to be quite popular.
The easiest shared decks to recommend are the ones based on the smart.fm decks, Core 2000 and Core 6000. These are particularly good because audio and image files are available to help you practice both reading and speaking/hearing. These core decks are following a study philosophy that's popular in SRS (spaced repetition system) circles of being sentence focused. AJATT covers some of the reasons for this.
Another alternative study method is MCD. It addresses a few concerns about a sentence focused method by giving you more context that a given kanji fits into. On the flip side of this, MCD is really designed for studying kanji, and I'm unsure if it provides any benefit for studying the grammar or spoken aspects of the language.
