Hi,
Unfortunately without looking at the code we won't be able to give you the css you will need to cover up the titles. You could of course make the easy modification yourself.
To modify and customize your theme's CSS, we recommend that you install and get to know Firebug and/or Google Chrome Developer Tools - both a free browser add-on. Firebug is a free web development tool that integrates into Firefox and Chrome browsers and assists in monitoring, debugging and editing of any website's CSS, HTML, DOM, and JavaScript files.
Watch this easy to follow 7 minute video – http://vimeo.com/20917974 – then install Firebug and you will be on your way to customizing your theme as you see fit!
Thanks,
Nick
