I got the manga (collections) and the short story/novella books through Amazon Japan. But last year when I was home in the States, I was realy surprised to see DVDs of the movies and English versions of the manga in a local media store. (I think it was an F.Y.E. I don't know if that's a national chain or just a Midwest one. I didn't check to see what they had while back this year.) And I found English translations of the books in a local Borders.
If they had them in BFE Ohio, surely someplace has to carry them up where you are.
