Nausicaa the comic is incredible, beautiful, bigger story than the film, and has deeper worldbuilding. I second the recommendation. Miyazaki has also two books with collected essays/articles of his; I have the first one and I would not strongly recommend them though they have wonderful sketch art inside. The essays are mostly old man rants about how everything is done worse these days and they weren't even written recently.
