Website bookmarks as a custom post type

Question

Let me first explain what I am wanting to do...

I am wanting to add all my hundreds of website bookmarks that I have now in my browser, into wordpress for the following reasons.

• Can search my bookmarks by category
• Can search my bookmarks by tags
• Can search my bookmarks by description and/or name
• Can access my bookmarks from anywhere
• Can add a description to all my bookmarks
• Can add a screenshot image if I choose to (least important idea)
• Will have a custom template for viewing the bookmarks which will look different from a regular blog post/list

And what I have done so far...

• Created a new post type "Website Bookmarks" with the code below

functions.php

<?php
/*
*  Add custom post type
*  name: website_bookmarks
*/

function bookmark_post_type()
{
    // Set some labels for our bookmarks post type
    $bookmark_labels = array(
        'name' => _x('Website Bookmark', 'post type general name'),
        'singular_name' => _x('Websiteite Bookmark', 'post type singular name'),
        'add_new' => _x('Add New', 'Websiteite Bookmark'),
        'add_new_item' => __('Add New Website Bookmark'),
        'edit_item' => __('Edit Website Bookmark'),
        'new_item' => __('New Website Bookmark'),
        'all_items' => __('All Website Bookmarks'),
        'view_item' => __('View Website Bookmark'),
        'search_items' => __('Search Website Bookmarks'),'not_found' => __('No website Bookmarks found'),
        'not_found_in_trash' => __('No Website Bookmarks found in Trash'),
        'parent_item_colon' => '',
        'menu_name' => 'Website Bookmarks'
        );

    $bookmark_args = array(
        'labels' => $bookmark_labels,
        'public' => true,
        'publicly_queryable' => true,
        'show_ui' => true,
        'show_in_menu' => true,
        'query_var' => true,
        'rewrite' => array(
            'slug' => 'bookmark',
            'with_front' => false),
        'taxonomies' => array('post_tag', 'category'),
        'capability_type' => 'post',
        'has_archive' => true,
        'hierarchical' => false,
        'menu_position' => null,
        'can_export' => true,
        'supports' => array(
            'post-thumbnails',
            'thumbnail',
            'excerpt',
            'custom-fields',
            'editor',
            'title'
        )
    );

    register_post_type('website_bookmarks', $bookmark_args);
}

add_action('init', 'bookmark_post_type');

And then what I need help/ideas with...

This gives me a custom post type, so I can add my bookmarks as a post, and search them and all that good stuff, also lets me easily keep them out of my main blog loop, so I can keep them more private if I choose to. Also let's me easily create a template page just for the bookmarks.

Questions

1. I would really like to be able to tag my bookmarks, many bookmarks will have more then 1 tag, example a site about PHP and MySQL and javascript, would be tagged with all 3 of those terms/tags. I know wordpress has tags built in already and I utilize it a lot on my current blog posts, should I add a NEW taxonomy ie. "bookmark_tags" because when a user views a tag page right now, it shows all my blog posts for that tag and I do not want a PHP tag page to show all my post's tageed with PHP and all my bookmarks tagged with PHP on the same page, so is the best method to create a new taxonomy called bookmark_tags?

2. Same exact question as question number one (1), except in regards to Categories instead of tags?

3. Any other Ideas or suggestions to improve my bookmarks section?
