Make menu centered and have two logos

Hello!

Totaly in love with the Sparkling theme. Where good work guys.
I need some help with

I want to make the navbar centered and make the width for the navbar-brand little bit smaller. Also I want to have an h1 on the right of the navbar.
Today it is like this: Navbar-brand ------ Menu item1, 2, 3, 4
I want: Navbar-brand ---- Menu item 1, 2, 3, 4 – h1-header

The h1-header should be in code. So no need to edit it via WP-interface.
