Navigationt design help

Hi All

I am trying to create a newspaper site which has various sections. Each section will have its own homepage and select content from each section will be displayed on main home page.

The site will have a standard header with a navigation system where there will be one horizontal bar with main sections and second bar with child menu/ sub sections i.e something like navigation system as given in timesonline.co.uk

Now my question is how to build navigation system in Drupal ? using primary menu / secondary menu or using menu block or using taxonomy system. I also wish to display breadcrumbs. So kindly advise as how to go about it and take which path for building navigation system and use which modules to get this kind of navigation system.

I also wish to know as how to get a navigation header bar like times.co.uk where child navigation is not dropdown but fixed and displayed on clicking the parent link. Is it possible to build that using jquery? any module for that?

I am quite novice is drupal and php and just trying to learn by going through the posts and module and so far deeply impressed by it.

will be very thankful for all the help.
