Re: Can the naviagtion change once the user has logged in? (Removing the HOME button)
At the minute once the user logs in it redirects the to their profile page. How and where do i include that code so the home button disappears?
Those are two different questions. 
Login With Ajax would help with the redirect. https://wordpress.org/extend/plugins/login-with-ajax/
As for the home button, in your header.php you just wrap is user logged in around Home. See https://wordpress.org/support/topic/367625?replies=5 for a bit more (and some oddities people are having with it…)
