in admin control panel, go to your styles and settings, edit templates
find the one that says navbar
look for
<!-- nav buttons bar -->
copy the code in between these comments into a txt file or something
<!-- / nav buttons bar -->
edit it as you like, replaceing the drops downs with your links and duplicating them as many times as you need to get as many drop downs as you need
paste that code you modified
above whats called breadcrumd
that will move it on top....look for this comment in that template
<!-- breadcrumb, login, pm info -->
if you need 2 rows of that navbar area like he has, just do it twice
like...
<!-- nav buttons bar -->
code for top custom navbar
<!-- / nav buttons bar -->
<!-- nav buttons bar -->
code for 2nd row of drop dropdown menus
<!-- / nav buttons bar -->
probably need a <br /> or 2 after this to distance it from the breadcrumb area
if you need to see his exact code, just view source

good luck!
