webdesinz on "Changing Font and size in Attitude Theme"

Hi I have installed Attitude which is a lovely theme.
I cant find out what they charge for their Pro version as they dont publish the price or reply to emails. I would however like to amend the font myself for free, since I know how to add Custom CSS styles but I am a little confused what to paste in because firebug shows the fonts name as "inherit" which I didnt think it was an actual font name. Using firebug I also cant locate the page title font sizes so I can change to custom size H1. So I am not sure what to amend. Can anyone assist? I have searched for any previous questions about fonts in the wordpress forum.
My web client is very happy with the theme, but does not like the font type and the page name titles are not in H1 so they are not big enough.
I am beginnning to think, that the fonts are blocked from customising deliberately so that the authors can charge for premium support to write the css amendment for us. I am wondering if anyone can isolate these css items for me so I can assign another font and apply h1 to page names titles.
