I have one styling request and one issue within the Product theme?

I am using the Product-child theme and I have selected the default.css in Preset Styling.

I have minimal plugins installed as I have had real trouble with the first two themes I installed from WPMU Dev. - Upfront-Fixer [see my other ticket] and GridMarket which gave erratic text and error messages all over the pages. And I did a fresh install of WordPress to eliminate database corruption from the two previous themes.

First the Styling Request:

How do I remove the Site Title in the Header? or at least use text other than the Site Title that is taken from General Settings?

Appearance > Theme Options - I can only select and modify the Slide One Tab. Other tabs show as a clickable link but nothing happens when I click the link. I have provided Support Access if needed.
