Well, I started with the book "How to draw Manga #1", it has 6 issues I think, and the first one is about the very basics, and all is very well described (I love it how they explain you how to proper draw a body in motion).
And I had a few sites with drawing info, but I can't remember, so I will post only these:
"What about us lesbians? . . . Your gonna burn in hell of course!" - MXC
"Hey dont knock masturbation, its sex with someone I love!" -- Woody Allen
"Evil will always triumph 'cuz good is dumb!" - Dark Helmet
Well, I don't think there is any difference rather than the coloring of Anime. Well, Manga has more "action lines" which are supposed to be the action in Anime (heh ^^).
But I don't know... this could be all wrong... I think...
