Was able to answer my own question. Here is my working code.
//Login Toggle
$('#my-raveis-login').click(function() {
if ($('#login-box').is(':hidden')){
$('#login-box').fadeIn('normal');
$('#login-box').find('.login-toparrow').fadeIn('normal');
}
else{
$('#login-box').fadeOut('normal');
$('#login-box').find('.login-toparrow').fadeOut('normal');
}
return false
});
//Prevent slider if login is open
$('#home-slider a.featured').click(function(e) {
if ($('#login-box').is(':visible')){
e.preventDefault();
$('#login-box').fadeOut('normal');
$('#login-box').find('.login-toparrow').fadeOut('normal');
}
});
It kind of duplicates some of the code for hiding the login, but it definitely works. Feel free to post if you have a cleaner way of doing this.
