Fixing some issues on a JustHost website

Memorial site for my father - I need someone to fix some relatively minor issues on the site:
-Replace two links
-Fix the Guestbook feature (will require installation of PEARs)
-Fix the page counter
-Verify that the Contact Webmaster feature works - if not, it needs to be fixed
-Re-place text in a few places (edits/corrections)

Thanks.
