support, I need some help with upfront. I installed

Hi support,

I need some help with upfront. I installed the spirit theme then proceeded to edit this page http://299websites.com.au/who/ to create my desired design/layout. Somehow things have gone wrong as I find when I visit another page eg: http://299websites.com.au/how/ http://299websites.com.au/faq/ http://299websites.com.au/contact/ and make content changes those changes happen globally across all the pages?

When I go back to http://299websites.com.au/ my header changes are lost?
I have setup a menu / header in the top 3 regions of this page http://299websites.com.au/who/ how do I make these regions display Globally?

Is there anyway to style the menu without learning css?

Is upfront compatible with all of your plugins? I want to use marketpress, couresepress pro, membership pro, pro sites, domain mapping, forums, whmcs mu/wp , support system, events + and more.

Thanks!
