Need Help With configuring my Theme ( site). (with Primary and secondary links and an archive page)

Ok, i will try to be brief and clear as possible.
In Danland theme which i use on my drupal 6.x machine,
(1) I can easily place an item (page, story,) etc on my drop down menu on my home page. But the problem is i cant seem to make this item hold another item(items) in such a manner that clicking the first item opens up a list of pages or another list of items. I guess all i want is just to learn how to make a real drop down menu with my "drop down menu".
(2) Secondly, i can easily make a "page"...or a "story" that allows comments. The problem is i dont know how to make another page, like an archive page...where i can place all the pictures AND THIER COMMENTS (very important) in a table-like pre-viewable manner. (like what you see when you go to this site: www.say-blu-ray.com )?? Like placing a lot of pages (or stories) inside another page (or story).
THanks so much for your anticipated answer.
