Question : How do I remove these menu items in wordpress

I am trying to achieve something quite simple in wordpress and cannot find where to do it.

If you go to my layout here:  http://avitalsheffer.com/cv/

I want to REMOVE the pages, archives, categories and Meta menus.

where on earth can I do this in the administration panel?

Can you also NOT have a header.  I essentially just want a very blank page with nothing much shown so I can include it into an exising html design I already have.

I hope someone can help

Answer : How do I remove these menu items in wordpress

Let's start with the header

1. Go to:
Control panel of your WP Blog > Appearence > Editor
On the right side select "Stylesheet" (style.css)
In this file scroll until you find : (on line 244)

#header {
background-color:#73A0C5;
height:200px;
margin:0 0 0 1px;
padding:0;
width:758px;
}

Replace this code with this one:

#header {
background-color:#73A0C5;
display:none;
height:200px;
margin:0 0 0 1px;
padding:0;
width:758px;
}

essentially what you do is adding "display:none;" to that style

you can do this to the side bar as well

scroll until you find:
#sidebar

and add

display: none;  

between the { }

2. More appropriate option to remove the sidebar widgets is to go to :
Appearance > Widgets

remove all the widgets from the sidebar. For instance : Pages - click Edit > click Remove > click Save Changes
