help with custom php for thematic framework theme

I'm working on a thematic child theme and need some help with some custom coding in the functions.php file.

1. for submitted posts, replace the post title on index, category, archive and single post pages with the first linked text from the post area.

2. within the post area, display a linked screenshot of the webpage linked from the first linked text in the post area by tying into the Wordpress core as described here: http://www.binarymoon.co.uk/projects/bm-shots-automated-screenshots-website/

so if there's a link like this <a href="http://www.bbc.co.uk">BBC website is here</a> then the post title becomes "BBC website is here" and the post contains a screenshot image of the website www.bbc.co.uk.

Ideally I'd like to achieve all this using hooks / filters... anyone able to help?
