Some download manager questions

first question

Often visit forums that has downloadable files on the site. What is the most efficient way I can download the webpage inclusive all the attachments. Is it possible that when I look in the downloaded site within Devonthink that when I click on the link (to the linked file) it saves it automaticly to the desk top or when I click on the link (after importing it in Devonthink) is it possible to click on reveal so it shows the attached file? All for offline reading purposes.

second question

Is it possible to download a complete thread the same way? Most threads I read have more than one page.

/showthread.php?t=5984&page=2&pp=20
/showthread.php?t=5984&page=3&pp=20
etc

Is there a way i can make the download mananger automaticly download all the following pages off a thread (with the same Idea mentioned in the first question)

Many thanks

Bob
