Article Suggestions - Header look

Hi,
I'm trying to get the header look like my menu but can't get it right...
My website :
http://serveur.dessouris.com/index.php/en/best-practices/asset-management/security

In the menu, I use a simple png to get the gradient, I can't get it to work with Article suggestions..
+ I need the hoover to be blue, like in the submenu.
+ I need the titles of the other section to appear without any highlight of any kind, like in the menu.

Another problem : the link seems to be working only when I click on the article title, I'd like it to work on the description too, since the cursor changes to the hand there too...

Any help would be appreciated!

Thanks

Max
