Answer 1

there are two way to put limit on collection.

 $tagId = 1; // I want to get id on view.html 
        $collection = Mage::getResourceModel('tag/product_collection')
        ->addAttributeToSelect('sku')
        ->addAttributeToSelect('name')
        ->addTagFilter($tagId)
        ->setPageSize(8);

or

$collection = Mage::getResourceModel('tag/product_collection')
        ->addAttributeToSelect('sku')
        ->addAttributeToSelect('name')
        ->addTagFilter($tagId);
$collection->getSelect()->limit(8);
