Joomla 1.5 Problem With Menu Item <li> Being Marked Current with id#current

I have a main menu that I positioned at the top of my template and styled with tabs. Its easy to make a selected tab appear selected, Joomla marks <li> with an id#current.

I also created a new menu in a column called "Services". I have all the services listed link to a specific article about that service (Article Layout) Each article is in Section>>Services, Category>>Services

One problem occurs when someone clicks on one of the links in the Services menu. Nothing in the main menu gets id#current and all of the tabs appear unselected.

I tried putting an menu item in the main menu titled "Services" and making the type Articles >> Category Blog and it didn't work. When an article in that category was selected in the Services menu, it didn't get id#current in the top menu. I also tried making it type Articles >> Section Blog. Didn't work.

Even worse, when I click on a service in the side Services menu, the url is mydomain.com/service-explained.html. But when I click on Services in the main menu, and then click through to a service, the url is mydomain.com/services/51-service-explained.html. This creates a major duplicate content issue.

How can I solve this problem?
