remove search bar/extend widht title on header of Pictorico theme

First of all sorry for my bad English and my limited knowledge of WP but I’m really a beginner… ??

This is the help that I need:
My theme is Pictorico and I want 1) to remove in header the “search box” 2) increase the length of the text box of the site title 3) remove from footer the functions: “recent posts”, “archives”, “categories”, “meta”.

I am adapting Pictorico theme for a site and don’t need blogs fuctions.

I hope I was clear and that advanced users can help a novice like me ??
Thanx
