I think I'm on the right track. From reading up on how .htaccess works, I added the second and third RewriteRule:
# Articles / Articoli
RewriteRule ^Article([0-9]+)\.html$ modules.php?op=modload&name=News&file=article&sid=$1&mode=thread&order=0&thold=0 [L,NC,NS]
RewriteRule ^Article([0-9]+)-([A-Za-z=]+)(-order([0-9]))?(-threshold([0-9\-]{1,2}))?\.html$ modules.php?op=modload&name=News&file=article&sid=$1&mode=$2&order=$4&thold=$6 [L,NC,NS]
RewriteRule ^Article([0-9]+)-Page([0-9]+)\.html$ modules.php?op=modload&name=News&sid=$1&file=article&pageid=$2 [L,NC,NS]
RewriteRule ^Article([0-9]+)-Page([0-9]+)-([A-Za-z=]+)(-order([0-9]))?(-threshold([0-9\-]{1,2}))?\.html$ modules.php?op=modload&name=News&file=article&sid=$1&mode=$2&order=$4&thold=$6 [L,NC,NS]
It doesn't redirect like http://www.freesitescripts.com/Article5.html does, but I can manually type in www.freesitescripts.com/article5-page2.html , I get the page, but missing images and styles.
Well, I'm going back to work on it. Could use some ideas!
Update: I don't know what I did but as you can see, the friendly URL is working. However, I still have no idea how to configure to create short urls in the << 1 2 3 >> thingy.
