I'm not a huge fan of the Heisig method. I started off with it, but I realized that a lot of the time, the key word I was learning for the kanji had absolutely nothing to do with any meaning or reading for it.
What I currently do is learn new kanji via Kanji in Context, and then create cards for them in my anki deck as I have learned them.
You might want to look into "Kanji ABC" by Foerster & Tamura. It was developed some years after Heisig and avoids using nonsensical keywords. I think their approach is better than Heisig if you already have familiarity with a decent number of kanji. The book is out of print so it may be a little tough to get a hold of (I found mine online at Powell's used bookstore). You can see an online version at work[1], but it isn't that useful on its own without the book.
