tons....dependz on the episode :P
Unfortunatly no, but the manga is good too.
Inuyasha (anime and manga) is about a half-demon dog, Wolf God (manga), but that's about wolfs, and Inubaka(manga).
I would recommend "A Kiss to My Prince."
This site is a good one for buying any manga or anime: http://www.justmanga.com/browse.cfm?anime=Wallflower
He's Dedicated to Roses is similar.
You might find Basara a good read, it's a romantic, historical manga with a similar war back drop.
I love the code geass anime, but I haven't read the manga. Is it any good? You can use http://www.mangahere.com/manga/code_geass_nightmare_of_nunnally/.
get (good) manga artists on board and have money. You can start small and informal, or make one just like you'd make any other company.
Yes, I would reccommend Lucky Star.
You can sometimes find manga in stores that sell American comics, also, Chapters, or any other major book store would be a good place to start, I know for a fact that at least the Chapters I visit has a manga section.
Any online manga source such as MangaFox.
There's basic Shonen(boy manga like Naruto and One Piece, Inuyasha etc.) Shojo:(girl manga like Hana Kimi, OHSHC, Kaze Hikaru etc.) Ecchi:(mature female manga) Seinen:(mature male manga) Joise:(mature female manga) some good free online sites that you don't have to download are Mangahut Onemanga Mangafox
