Allow Users Access to Custom Post Type Only

I am in a similar situation to this person, only I need a bit more hand-holding. I don’t have a good understanding of php but can cut and paste code with the best of them.

I have Justin Tadlock’s Members plugin, and have set up a custom post type and associated custom taxonomies in my functions.php file.

Here’s what I’m trying to accomplish:

• User registers and is set as
  Contributor by default.
• User can now see only this custom post type
  and can make an entry to this post
  type, but not publish it.
• User can only see and edit their
  own post(s).

If possible, I need specifics on what and where to add to my post type registration function. I understand it involves ‘map_meta_cap’ and ‘capability_type’ but I don’t know how to write the code or where to put it in the function. Once the capabilities are established I can add them as custom capabilities in the Members plugin.

I figured it out on my own — the code snippet I needed to follow is here. Justin Tadlock is the man.
