You should check zeList plugin
http://wordpress.org/extend/plugins/zelist/ which includes some of the
things you're looking for.

For link extended fields, I strongly recommend the creation of a
link_meta table (aka option 2), and duplication of post_meta
functions, for two reasons :
- adding the table and copying the functions takes 30mn top.
- if and when WP decides to switch to a taxonomy-neutral meta table it
will be easier to switch from a "roughly similar to postmeta "
architecture than from a custom hack.
In zeList, just check zelist/includes/metas.php for the functions and
zelist/zelist.php (function zelist_install) for the database creation.
You may need to work on the Link Edit Page to add custom metas fields,
since I did not add these.

As for link related to posts, it can be done manually, or automatically.
Check http://cadeaux.laporterie.com/camping/18-acheter-une-caravane.htm
(check "Liens connexes") for an example of zeList in action. The
function is "related_links()" in

For the description/title/images parsing, check
it includes a zelist plugin (zelist-submitter), not released yet,
using the zeList API.

Let me know if some of that is helping you !
