1. You should be able to do that using pages. Set up a new page and have it redirect to the RSS feed. In your case, that would be http://eatingwithmeaning.tumblr.com/rss.

  2. If you’re willing to dig around in the code, you can do this by going to the area just under {block:Text} and replacing this:

    {block:Title}<h2>{Title}</h2>{/block:Title}
    

    with this:

    {block:Title}<h2><a href="{Permalink}">{Title}</a></h2>{/block:Title}
