Limiting theme edits

Hi,
Multisite 3.1.2

I want to restrict theme edits on GridMarket.
I can use new blog template and menu editor plugins so that nobody can edit widgets, menus, certain pages etc, but I also want to restrict Theme Options in the dashboard because it has links to widgets, menus etc.

I only want to give the sub store the ability to enter its name or logo on Dashboard>Theme Options

"These simple options will allow you control over some areas of your site.
Type of header Select one Text
Custom Header or Logo *we use the custom header to allow you control over logos
Site Title
Enter some text for your site name Site name"

How do I prevent sites from seeing the rest of Theme Options?

Thanks!
