Add this in conf/hacks.php, if the file is not there - create it.

global $DB;

$DB->query('DELETE FROM T_comments WHERE comment_status = "draft"');

Then open any blog page to run the script.
Don't forget to delete the file once comments are deleted.

It's always a good idea to backup the database before running my free-typed scripts :)

I'd just like to know how to quickly and simply delete all the comments awaiting moderation. I've been deleting/reporting spam comments all morning and I am sick to death of it. Any help would be appreciated.

Boy, I know this feeling. For the past hour, that's all I've been doing.

Thanks Sam -- but how am I to know that is legit?

well, another way is you copy the content of that page, paste it and create a fresh page and publish it. now that you have a duplicate page with the same content, you can delete the old one and all the comments get deleted too! :)

There's a tool to delete all spam comments and/or hits. Check the Tools > Antispam > Tools tab
