Problemas na tela de login

Olá, gostaria de saber porque a requisição ajax, está dando erro(e as possíveis soluções). É assim, basicamente o usuário entra no site e loga(duh) e então começam os problemas.

Na teoria ao logar, a página de checagem recebe os dados faz a filtragem e então ele, teoricamente deveria voltar os dados e aparecer uma de sucesso ou falha, mas acontecem alguns problemas,

	Primeiro que se o user/password estiver errado não aparece a mensagem de erro (User/Senha Inválidos!) e nem fazer nada(clica no botão login e não faz nada);

	Segundo que a velocidade de redirecionamento é muito rápida(nem da pra ler User/Senha Corretos. Redirecionando ...), gostaria de tar um tempinho e aí redirecionar;

	Terceiro eu não sei muito de ajax por isso, poderão ter erros muito óbvios que eu não percebi, e se tiverem sugestões por favor digam também se quiserem

	 

	Código da página de login:

	 

<?php
session_start();

if(isset($_SESSION['logado']) && $_SESSION['logado'] == 'TRUE'):
	header("Location: index.php");
endif;
?>
