Joomla not showing articles
===

Am working on my first joomla site, so im kinda hacking my way through it and i thought it would be good to learn by modifying.

First of all i would like to apologize for posting this here, its that answers here flow way faster than on joomla.org.

For reference, [This][1] is what the site looks like, 

[here][2] is the index.php 
and 

[here][3] is the current template.css being used.


My problems are as follow:


1:
Using the first menu, [Quem Somos] as example, ive created a category and under it ive put some articles. Using the default mod_mainmenu, how would i make it display a dropdown menu?

 i cant do it even if the primary menu items are created as lists of categories or, when the submenus are linked directly to articles and then these submenus are linked to a primary menu, the module just shows that one level pill menu shown. Do i need an extra module or something? am meddling with swmenufree but am guessing something basic as a dropdown menu fed by a category/section is something that should be built in.


2: 
In my quest for a 3 column template ive most definitively destroyed something and now whenever i click any link (all links have articles to back them up) the site just shows the same main page. clicking and typing (c&p actually) the entire url in the address bar gets me nowhere also. The url it shows is correct but what i keep seeing is the landing page
