Showing multiple custom post excerpts

I have created custom post types with the Custom Content types plug-in. I want to show excerpts of the posts created with this custom type ('orange-papers') on a WP page ( not post ). I have a template for that setup.

1) How would I do that?
2) Do I need to attach the Custom Post Type to a category?

3) Can I somehow just show a finite number of them as excerpts and then do "read- more" links to the full post?
