I want a RSS link where the link to my pages are blogroll

I want to but the link to my RSS feed after the links to my pages, but I’m no code genius (although I thought I was better than this…), and mess up the code when I try to insert the link.

This is the code that’s there already:

// Default Main Nav Function
function default_main_nav() {
echo ‘<ul id=”main-nav” class=”clearfix”>’;
wp_list_pages(‘title_li=’);
echo ”;
}

Where and how to I put in the RSS feed link?

And a different coding problem:

I’ve put this code into my blogroll page:

< ?php wp_list_bookmarks( $args ); ? >

(without the spaces after and before the tags), but nothing showes up. What have I done wrong?
