1. you say to add urls to "extra_urls.txt" - the zip I downloaded didn't include that so I'm unsure where it should be and how the URL's should be entered.

This file is located in vbseo_sitemap/ folder (it's empty by default) and you may add additional URLs in "url,frequency,priority" format, like:
http://yourdomain/page.html,daily,1.0

2. your instructions say to chmod the data directory--you might want to tell people to create it as well, since it isn't already in there. It's fairly obvious, but still

"vbseo_sitemap/data/" folder is included in the zip archive. It is empty - may be your archiver software doesn't extract empty diretories? (btw, "extra_urls.txt" file is also included in archive )
