Problems with navigation/menu:blog.page.book,forum? what is best?

I am trying to set up a navigation system
with Drupal,......... distinguishing between
Forums, Blogs. Books, Pages, is not all that
clearly defined. ........Help!

I want to use Tabs running across the top of the
site, similar to this

http://deltaguitar.ning.com/

I just dont know whether to use Books, Forums, Blogs

The Menu titles will be like this:

Delta Blues.. Texas Blues ..Ragtime Blues.. Other....Gear

Then the categories go into the artists,

Delta Blues (has a subcategories of)

Mississippi John Hurt
Son House
Bo Carter
Robert Johnson
Willie Johnson

Mississippi Fred Mc Dowell

Then each of these artists
have subcategories which will be the songs they wrote

Mississippi John Hurt (has a subcategories of)

Monday Morning Blues
CandyMan Blues
Avalon
Payday

Frankie and Johnny

and each song here has a pdf which can be downloaded
which has the transcription of the song and most times a
embedded video.

So one issue is just getting the top navigation items to appear
across the top where they are accessed like tabs,...
I wonder if I should mix up formats or stick to one,
like Forum or Book,
the other issue would be
getting this to appear after
clicking the Tab Delta Blues:

Delta Blues

Mississippi John Hurt
Son House
Bo Carter
Robert Johnson
Willie Johnson

Mississippi Fred Mc Dowell

Maybe I should use CSS w/ a
ordered or unordered list?

Also I would like actual block Tabs how is this done? CSS, a module?

This is the site ,

I have been learning Drupal for about 3 weeks & my first CMS,
I think its great.

Thanks
