I am planning to render Houdini 's scene with renderman. How should I start? Is there any tutorial talks about it? I also want to learn how to make a renderman shading network with Houdini. Will that shading network work for other renderman renderer other than prman?

Try Alex's tutorial on setting up renderman with houdini first or you'll be tearing your hair out before you know it:
