help please with menu/nav for a music instructional site?

I am trying to set up a navigation system now,
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 my site I am working on,
I have been learning Drupal for about 3 weeks & my first CMS,
I think its great.

Thanks
