Try this link for some really great kanji books by Bonjinsha:

They are much better than any kanji books you will find state side. Unlike most books, they actually have exercises where you actually write and use the kanji in sentences and context, as opposed to just memorizing them (which isn't an effective way to retain them). So far, this is the best, most effective book I have found.
What's great is that the kanji covered correlates with the JPTL Level 3 test. After you master these two, this seriess also has some higher level books for JPTL Level 2.

Minna No Niho-go also has some good kanji books to go along with their text book, and both 1 and 2 covers most of what you'll need for JPTL Level 3. While Minna no Nihon-go is good, I don't like how you have to buy so many seperate books (Main text book, then grammar explanation book, then several different types of kanji work books...it can really add up money wise).
Here is another good one for beginners:

It is loaded with exercises...my only complaint is that they only released one book in this series...I really wish they have released more advanced editions for JPTL level 1-2 exams. Otherwise, it's a great place to start.

For kanji cards, I find the ones by White Rabbit Press to be the best:

They also have higher levels too for JLPT level 1. They are expensive, but they're imo the best flashcards I've seen out there, and they have vocabulary on the back of each kanji card, which is very helpful.
Kondasha's products are also good, but I think the Bonjinsha/White Rabbit items are superior...
