Just looking for a text book or two to read and learn from on and off. Its nice to get away from the anki and the online resources for a bit and let my eyes read something thats not back lit.

Any suggestions for textbooks that uses full kanji or furigana?

Genki I and II are pretty good textbooks, especially with the CD's and workbook. They have vocabulary, dialogues, practice exercises, and grammar, and they do use kanji/furigana.

I'd say the two best beginners textbooks that are written in Japanese script are Minna no Nihongo and Japanese in Mangaland. Minna no Nihongo is probably harder without a teacher, so Japanese in Mangaland might be the way to go.

I'd probably put Genki as third.

Cool, I was thinking of getting some books as well. Want to do some work outside anki/computer.

I can't comment on anything other than Genki and An Integrated Approach to Intermediate Japanese (IJ), because that's what we used in class.

I, for one, thought Genki was wonderful. You may not get a whole lot of vocab (lawl, turbo adding 100 cards/day!!!!) but the words that you do learn, you'll a good amount of practice with -- along with the CDs and Workbooks, that is. I also had a class with good teachers, so that also may have added to it.
The grammar explanations are pretty simple, but I didn't feel they were oversimplified.

IJ is by the same publisher and the unofficial sequel to Genki. It follows a -roughly- similar format (kaiwa/yomimono, vocab, grammar, exercises) but there are no common characters throughout.
They crammed the grammar in this one. Take the amount of grammar points in Genki (a couple per chapter) and multiply it by a couple, and you'll have IJ (one chapter has 12 points, one has 9, although some have less). Sometimes it feels like the descriptions are lacking -- but they probably make up for it in the exercises maybe....
I was taught by the professor who actually wrote the book, so that might have made my experience of the book better than someone self-learning, however....

That's really all I've got about textbooks. If you have any more questions about either of them, I can definitely elaborate on it.

I remember researching about textbooks that give you a format/examples of how to write formal letters in japanese. And another book on emails,etc.

Here's one
