In San Francisco I picked up this book. While it is definitly playful and aimed at children, it is a wonderfully effective way to learn Hiragana. (The bookstore had copies of it in both the "Learn Japanese" and "Children's" sections...)
Last night I downloaded Adriaan's awesomely powerful "Kotoba" application as well. I say powerful because you can access web-available "Lexicons" as well as import user-created ones (though cross-checking the Hiragana-Katakana one with the Monkey book, I noticed it is totally wrong... damn...). Shameless plug: Adriaan is also the developper of the fantastic "ecto" Mac-based weblog editor. Adriaan is also a crafty monkey. Hehehehe.
Anyways, once I am through those two, I will use Nuku Japanese kana tutor to do reinforcement testing. Perfect!
Then I'l have to learn what the hell I am reading actually means!
Start slowly.
