Answer 1

Step 1: Controller (IndexController.php) file In index controller simply load the layout and render it.

<?php
class Abc_Example_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()
    {
        $this->loadLayout();
        $this->renderLayout();
    }
}
?>

Step 2: Layout (custom.xml) file Put the under given code in the layout file of module.

<?xml version="1.0"?>
<layout version="0.1.0">
   <example_index_index>
       <reference name="content">
           <block type="example/collection" name="collection" template="example/collection.phtml" />
       </reference>
   </example_index_index>
</layout>

here is code for block where you can define collection

<?php
class Abc_Example_Block_Collection extends Mage_Core_Block_Template
{
    public function __construct()
    {
        parent::__construct();
        $collection = Mage::getModel('example/collection')->getCollection();
        $this->setCollection($collection);
    }

    protected function _prepareLayout()
    {
        parent::_prepareLayout();

        $pager = $this->getLayout()->createBlock('page/html_pager', 'custom.pager');
        $pager->setAvailableLimit(array(5=>5,10=>10,20=>20,'all'=>'all'));
        $pager->setCollection($this->getCollection());
        $this->setChild('pager', $pager);
        $this->getCollection()->load();
        return $this;
    }

    public function getPagerHtml()
    {
        return $this->getChildHtml('pager');
    }
}

you have to define custom collection which return the product id as per your requirement.in above code here is the phtml file where you can get pagination

<?php echo $this->getMessagesBlock()->getGroupedHtml() ?>
<?php $collection = $this->getCollection(); ?>
<div>
    <h1><?php echo $this->__('My Custom Collection') ?></h1>
</div>
<?php echo $this->getPagerHtml(); ?>
<?php if($collection->getSize()): ?>
<table id="my-custom-table">
    <col width="1" />
    <col width="1" />
    <col />
    <col width="1" />
    <col width="1" />
    <col width="1" />
    <thead>
        <tr>
            <th><?php echo $this->__('ID #') ?></th>
            <th><?php echo $this->__('Title') ?></th>
            <th><span><?php echo $this->__('Created') ?></span></th>
        </tr>
    </thead>
    <tbody>
        <?php $_odd = ''; ?>
        <?php foreach ($collection as $_obj): ?>
            <tr>
                <td><?php echo $_obj->getCollectionId() ?></td>
                <td><span><?php echo $_obj->getTitle(); ?></span></td>
                <td><?php echo $this->formatDate($_obj->getCreatedTime()) ?></td>
            </tr>
        <?php endforeach; ?>
    </tbody>
</table>
<script type="text/javascript">decorateTable('my-custom-table');</script>
<?php echo $this->getPagerHtml(); ?>
<?php else: ?>
    <p><?php echo $this->__('The collection is empty.'); ?></p>
<?php endif ?>
