If you want flat shading, yes you need 1 glNormal call for each face.
If you want Gouraud shading, you need 1 glNormal call for each vertex.
i have found GL_AUTO_NORMAL in internet,can i use it?
No.. thats for high order surfaces only ( spline surfaces)

To keep you sanity, you probably want to calculate the normals instead of specifying them by had http://www.opengl.org/discussion_boards/ubb/biggrin.gif.
