Hi,
sorry but we does not provide this kind of integration, but this seems something that already do Membership Pro. try to see at http://membershipprodoc.joomservices.com/synchronize-profile-data

Hi,
sorry but Easy Profile never expose usergroup informations (security purpose).

Anyway you can create a override and add a code to show usergroups, follow these steps:
1) Override Easy Profile Layout (to not loss changes when you update our component)
- copy /components/com_jsn/views/profile/tmpl/default.php into /templates/your-template-folder/html/com_jsn/profile/default.php

2) Add following code between line 101 and 102:

<?php

                // Access Levels of current logged in User

		$acl=JFactory::getUser()->getAuthorisedViewLevels();

                // Only admins can see usergroups, In default Joomla installations 3 is the a Special acl, you can check this ID from Administration->Users->Access Levels

		if(in_array(3,$acl)) {

                        // var $this->data->groups contains ID of usergroups of displayed user, so we need to get titles of usergroups from DB

			$db=JFactory::getDbo();

			$query=$db->getQuery(true);

			$query->select('title')->from('#__usergroups')->where('id in ('.implode(',',$this->data->groups).')');

			$db->setQuery($query);

			$usergroups=$db->loadColumn();

                        // Show usergroups

			echo implode(',',$usergroups);

		}

?>

NOTE: this code is not tested and not supported, this is only for example purpose
