Hi,

1. You mean you want to remove the comments from posts? Follow this http://en.support.wordpress.com/enable-disable-comments/
2. You want to remove the custom post type slug from the links? You can use some plugins to do, or get your hand dirty by editing the files http://www.itsabhik.com/remove-custom-post-type-slug/

Let us know,

Thanks,
laranz.
