Theme development

Hello,

I would like to modify the output of my menu, I need to create a really specifique one.
I am using sub theme "NAME_THEME" from Omega 3 on drupal 7 with omega tools.
I should override with the hook_links like this: NAME_THEME_links($vars)

but the system doesn't use my function, and I really don't know why. I debug and find only the hook of omega is used:

omega/includes/omega.theme.inc l.281 :

I'm delving into a HTML 5 conversion with Drupal theming and I have a quick (maybe) question. HTML 5 uses the new article section which seems to serve a similar function to the node class for theming. It seems somewhat redundant though and playing with it I run into some problems. If I theme article with say, a background, both the node and the article section get the background, so it's doubled. If I strip the article section and just theme the node, going to the page where the node is displayed strips the background completely, but the summary on the main page is themed.

I would like to get rid of the blog style main content on the homepage but Drupal is not allowing me to. It says it needs a main content type and always tries to post something there.

I would like to have my themed tool bar as the main subject of the page. I would like the page to be bare except for my tool bar which I am trying to place in the center. Should I create a new default page for this or should is there a way to make my module the main content of the page.

This site has a nice feature where you click on an item from the main menu (e.g. "awards") and a whole sub-menu with graphics drops down, pushing down the slideshow: http://www.dandad.org

Does anyone know of any contributed Drupal themes/modules or any other code widgets which will do this or something similar? It doesn't have to be a vertical drop, it could also be something that flips out of a side menu, for instance.

Thanks :)

I'm trying to get into advanced theming, and I see information on template.php scattered around, but I can't find a very good treatment of it - it appears to be related to all of the TPL files.

Are there any resources for it? I've searched the site for Drupal theming information, and I didn't find anything for Drupal 7 template.php information.

The primary menus break with different screen resolution on drupal-6.17. Everything looks fine when my screen resolution is set to 1920 x 1080 but if I switch to 1024 x 768 is breaks. I'm new with coding and drupal so any help would be greatly appreciated! Thank in advance.
