Job Search to be just on more than one page BUT not all (Very New at WP)

Hi,

I am struggling a bit with this. I am trying to set up a website for recruitment where the Search function would only be visible on the Candidates Section (public view) and the Recruiting company section (private view) – at the moment it appears on all pages. Also ditto with some of these text widgets and the listing widget – in fact how does one get rid of widgets. Finally I set up my pages but 3 appear in the menu (Sample CSS, My Account and Members appear that I did not set up) – All the menu items that I set up do appear but all together not parents and children so this is all doing my head in !

Any help would be much much appreciated !
