You can create two static blocks for this and put those static blocks in appropriate position in the layout.
Let us assume your static blocks are
header-phone. In that case, you can use the following code in appropriate position in
header.phtml(I am not sure about this template file. But most probably it should be the template file that renders those parts).
<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('header-phone')->toHtml(); ?>
<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('header-email')->toHtml(); ?>
You need to invoke this code snippets in appropriate postion in
header.phtml. Also you may need to do some css works in order to make them align well
Hope that helps.
