I would like to slightly edit a few things in the Vertex theme and I was wondering how do I go about doing the following:

1- Replacing the jscript main menu with a drop down menu as seen in the admin panel:


2- Changing the post body background color. [Without changing/effecting other parts of the forum].

3- Fixing some unaligned headers and bodies: E.g [*Tinyportal]
