You will notice that the Home tab actually is the first node and then has a child UL which represents the rest of the navigation Items. So the approach is to hide the first <li> <a> (display: none) and then simply just use (display:block ) to show the hidden <ul> <li> <a> tags.
Here is the CSS you could use to hide just the first node (home) tab in a SharePoint 2010 application:
.s4-tn li.static > a{
display: none !important;
}
.s4-tn li.static > ul a{
display: block !important;
}
Enjoy!
