There's a penalty on HN for items that don't have a link. You would be better served to write up your text on a web page and submit a link to it. Work hard on getting the submission title text right, and submit when the site is busy, but not swamped.
Your "landing page" can then have the links in it, and you can include screenshots as to why it's useful and/or interesting. In short, sell it, otherwise most likely no one here will notice.
