show user id in front end

Hi,
First let me thank you all for a great support, i have learned so much building my system, and when it goes live i will share it with you.
now for my question.

I would like to know if is there any why for me to present the user (after he logged in) every where in the website his hikashop_user_id.

I would like to know how to do that, as there are a couple of custom fields I need to present for the user but it's all connected to hikashop user id and not joomla.

Thanks for your help.

What about if hikashop is not loaded?
How do I load it in my module?

Thanks for your help.

What i meant was, if I wan't to display my module on the homepage, but there is no product/cart/ or any thing from hikashop.
How could I load fast with out needing to do some thing like that:

$user =& JFactory::getUser();
$usercmsid = $user->id;
$username = $user->name;
$jdb =& JFactory::getDBO();
$query = 'SELECT user_id FROM hikashop_user WHERE user_cms_id = '.$usercmsid.'';
$jdb->setQuery($query);
$user_id = $jdb->loadResult();

ok, I got it working.
here is how I did it:
first, we need to insert the hikashop helper:

if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php')){
echo 'This module can not work without the Hikashop Component';
return;
};

$userhika = hikashop_loadUser(true);
$user_id=$userhika->user_id;
