permalink migration advice with 2.3

hi there. I want to migrate my permalinks from the post id format to post title.

To avoid the loss of search engine page rank, I realize I need to use redirects so old links aren’t broken. What I’m unclear on whether I should use Dean’s ( http://www.deanlee.cn/wordpress/permalinks-migration-plugin/ ) or Scotty Yang’s ( http://scott.yang.id.au/code/permalink-redirect/ ) plugin to manage the redirects, or whether I don’t need it with the newest version of WP, as this article describes ( http://www.dnseo.net/wordpress-301-permalink-url-redirect/ ) I don’t need it because it’s all built into the latest WP.

So I’m not sure what to do, and thought I’d see y’all advice before I go down one path.

Lastly, I use feedburner for RSS feeds – and heard the plugins break those feeds. If doing one of the above 3 options, what do I need to do to make sure the feeds don’t break?

thanks.
