I added my own layer of css which allowed me to override some of the default styles to my liking. I used some simple PHP includes to manage items that were reusabale between pages and for a form submission. I also restructed the Header area so that my site branding was not inline in the NAV menu. Instead of div,div,div for the header structure I used more html5 symantic tags of header, nav, ul, with the appropriate boot strap classes.
