Answer 1

You can get the list of all the categories along with the url using the below code

This will display all top level categories:

<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php if (count($_categories) > 0): ?>
    <ul>
        <?php foreach($_categories as $_category): ?>
            <li>
                <a href="<?php echo $_helper->getCategoryUrl($_category) ?>">
                    <?php echo $_category->getName() ?>
                </a>
            </li>
        <?php endforeach; ?>
    </ul>
<?php endif; ?>

To display all top level and subcategories use below code:

<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php $currentCategory = Mage::registry('current_category') ?>
<?php if (count($_categories) > 0): ?>
    <ul>
        <?php foreach($_categories as $_category): ?>
            <li>
                <a href="<?php echo $_helper->getCategoryUrl($_category) ?>">
                    <?php echo $_category->getName() ?>
                </a>
                <?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
                <?php $_subcategories = $_category->getChildrenCategories() ?>
                <?php if (count($_subcategories) > 0): ?>
                    <ul>
                        <?php foreach($_subcategories as $_subcategory): ?>
                            <li>
                                <a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>">
                                    <?php echo $_subcategory->getName() ?>
                                </a>
                            </li>
                        <?php endforeach; ?>
                    </ul>
                <?php endif; ?>
            </li>
        <?php endforeach; ?>
    </ul>
<?php endif; ?>

Answer 2

you can do something like:

$root_category_id =  Mage::app()->getStore()->getRootCategoryId();
$root_category = Mage::getModel('catalog/category')->load($root_category_id);

function getCategories($category, $withSubcategories = false)
{
    $children = $category->getChildrenCategories();
    foreach ($children as $cat)
    {
        echo $cat->getName()."<br>";
        if($withSubcategories){
            getCategories($cat, true);
        }
    }
}

end after that if you need only main categories without sub-categories, only call:

getCategories($root_category);

and if you need with sub-categories:

getCategories($root_category, true);

of course you can format it as you want. This is only example how to fetch and echo catgories
