changing header info not found in appearances-editor-header.php

Hello, http://www.yeticooling.com

Presently i pay to have someone host my site and i am trying to make the adjustments i need due to a relocation and a busy webmaster. I have been able to change the footer, but i am stumped presently.

question 1)

How do I change the phone number listed horizontally along side the drop-down menu tabs?

Question 2)

How do i change the phone number located horizontally below along side the twitter and FB feeds?

Question 3) how do i go about gaining full control as well as FTP info so i might change hosting from an unwilling host?

thank you so much in advance. WP seems t be an amazing community and i am looking forward to learning the coding/poetry Thanks Yeti Brian
