changing colors of links in comments.php

Recently I installed the brians threaded comments plugin and now I can’t see any of my links on the comments – I can see most of the links, except for some of these (edit this, reply to this, etc.) Instead of editing the color in style.css I’d rather do it in comments.php. Can someone do a real quick markup of the small segments of code below so that I can know how to edit the rest.

<?php edit_comment_link(__("Edit This"), ' |'); ?>

<a href='#' onclick='moveAddCommentBelow("div-comment-<?php echo $c->comment_ID ?>", <?php echo $c->comment_ID ?>, true); return false;'>Reply to this comment</a>

Here is my full comments.php in a pastebin

Also if you look at

you’ll notice that the text in the comments is all bolded, while the text in the comments here is normal text
