I'm confused. You ask for the # of comments, but the code you pasted is for the view count. The comments themselves are already listed on the singleBody page anyway. But anyway, if you want to add the text you can add this:
{if $CommentItemDetails.totalComments > 0}
{g->text text="Comments: %d" arg1=$CommentItemDetails.totalComments}
{/if}
On line 90 of singleBody.tpl (right under where we print the "Owner:"). You can wrap the text in a <a> and have it link anywhere you want...
