Admin theme modifications

Greetings,

is there any module / theme for non-admin access? I mean, i need to create content-admin access for regular users which means to disable modules updates, warning/error messages, theme changes aso. Is there something i can use to get it easilly done or I'm the only one who need something like this?

Thanks for tip or link.
