you can get the customer details like below :

customer id here

$customerId = 1;

load customer object

$customer = Mage::getModel('customer/customer')->load($customerId); //insert cust ID

create customer address array

$customerAddress = array();
foreach ($customer->getAddresses() as $address)
{
   $customerAddress[] = $address->toArray();
}
