Adding snippet to default user profile theme (user_profile.tpl.php)

I have created a custom user profile based on the the default user profile theme http://drupal.org/node/154129. Obviously when this is used, all the fields are generated within the profile categories. This is what I want versus explicitly calling each profile field as in this example: http://drupal.org/node/35730

I'm not a PHP programmer in the least, so I'm not clear how I'd now add snippets to my custom profile. The snippet I want to include is the allow users to choose whether certain profile fields are visible or hidden. This example uses the profile_hide_mobile. Since my custom profile, based on the default user profile, doesn't explicitly call the fields, but rather generates them in a loop, can I use this snippet that allows the user to decide weather certain profile fields are visible or hidden? And if so, can some one show me the code? I figure if I know how to insert one of these snippets into the default user profile, I can do more.

Thanks!
