Mystique – RSS, Twitter, Navigation Buttons

Hi,

I just started using the Mystique theme and was wondering if there are is anyway too add buttons too the navigation, not the silver bar, but the icons that are on the top right of it.

so Far it has RSS, Twitter,

I would like too add others like Facebook, Myspace, YouTube, Email etc.
I know I will have too have my own icons thats alright.
Is there a plugin too add these, some sort of code or am I just completely missing the option in the Dashboard Settings
