Customising home page & right hand header

Hi My site is http://www.pricesoptions.com/ I've looked through instructions & FAQs and would like to know how 1. I remove the "Home" page title on the Home page (not the one on the navigation) 2. How can I replace the search bar on header's top right hand with a contact us button or social media button? 3. Also how can i remove the footer of my posts that refers to where the post is located and tags? Grateful for any help your can provide thanks Irene
