Customize the menu by adding items

Question

I need to display a simple menu like this:

<nav class="main">
<a href="/" class="home">
    <span class="logo"></span>
    <span class="company-name">My Company</span> 
    <span class="page-name">Home</span>
</a>
<a href="one-page">One page</a>
<a href="two-page" class="selected-current">Two page</a>
<a href="three-page">Three page</a>
<a href="about">About</a>
<div class="account">
    <a href="login" class="login">Login</a>
</div>

For this I proceed in this way:

/theme/function.php

<?php
// Adding Log in/out links to a Specific WordPress Menu
add_filter( 'wp_nav_menu_items', 'add_loginout_link', 10, 2 );
function add_loginout_link( $items, $args ) {
    if (is_user_logged_in() && $args->theme_location == 'primary') {
        $items .= '<div class="account"><a href="'. wp_logout_url() .'" class="login">Logout</a></div>';
    }
    elseif (!is_user_logged_in() && $args->theme_location == 'primary') {
        $items .= '<div class="account"><a href="'. site_url('wp-login.php') .'" class="login">Login</a></div>';
    }
    return $items;
}

/theme/header.php

<nav class="main"><?php
$menuParameters = array(
  'theme_location' => 'primary',
  'fallback_cb'     => 'starkers_menu',
  'container'       => false,
  'echo'            => false,
  'items_wrap'      => '%3$s',
  'depth'           => 0,
);
echo strip_tags(wp_nav_menu( $menuParameters ), '<a><div>' );
?></nav>

I can not manage the class pages for current and the tags (span) for the first url (home).

Thank you in advance for your help.
