[support] News and Services in the menu

Hello All: I just installed drupal and looking to get a website running. I still have a lot to learn. I want to avoid using any additional modules. One of the requirements is to create a menu item called "News". This will display a page of all the available news for the site. I like to have the ability to create a news page granted for news editors. Similarly I need a "Services" item. Using taxomony and content types, this should be possible. Right ? for example, I created an vocabulary called "News" with one term only "default" to be applied to a page. Is there a way to create content type for news only ? and How to add this to the menu ?

Any ideas or tutorials about how to proceed ?
