if ($_SESSION['login_count'] >= 3 && $_SESSION['suspect_user'] = 'Suspect User Good') {
here's one problem - this part:
$_SESSION['suspect_user'] = 'Suspect User Good'
sets $SESSION['suspect_user'] to be 'Suspect User Good'
you want
$SESSION['suspect_user'] == 'Suspect User Good'
Double equals for a comparison.

Not surprised you're going cross eyed - indent your code and add line spaces to make it readable!
Also you may be busy but so's everyone.
You think the PHP is simple and HTML /CSS complex advanced stuff? Hmm, which makes the site work?
