Joomla SEO project with tourist site

Having problem with getting OpenSEF to work on joomla 1.013 - getting 404 page not found. Here are the problems listed: 1. The URL should be automatically generated - with the structure /category/title as configured in opensef but all urls on the web pages are not so friendly (no keyword) like "www.mysite.com/content/section/4/32/" which is the generic joomla core sef type url before even installing opensef. 2. When an internal Url is used to access to site, it is automatically redirected to the SEF url. But, the problem is that the redirected url got a 404. For example, if I typed in "[login to view URL];task=section&id=4&Itemid=32 " - it is I will be redirected to "http://rome.net/shopping-in-newyork/". But, the redirected page got a 404. The mapping is automatically added by OpenSEF in the SEF URL List. If I were to use the SEF Url "http://rome.net/shopping-in-newyork/", I'll still get a 404. 3. There may be problem with the htaccess file. I've followed the instructions in there quite carefully. This should be a pretty simple problem to fix for somebody who have experience with OpenSEF and Joomla. If somebody could solve this problem, and showed their expertise in SEO and Joomla, I've alot of websites waiting to be developed using Joomla and SEO.
