Answer 1

In Magento you can use one of below approach.

Option A:

1. Login into magento admin area
2. Go to System => Configuration => Customer Configuration
3. Create New Account Options tab and set "No" to 'Require Emails Confirmation' option.
4. Login Options and set "No" for 'Redirect Customer to Account Dashboard after Logging in' option.
5. Then open \app\code\core\Mage\Customer\controllers\AccountController.php

you can change it from this:

$session->setBeforeAuthUrl(Mage::helper('customer')->getAccountUrl());

To this:

$session->setBeforeAuthUrl(Mage::getBaseUrl());

Option B:

Create a custom module to work with "customer_login" event observer.

Option C:

Use the free community extension for logi redirect. You can get the idea from below one:
