Problem with fonts and styles

Hi there

First of all, great theme. I am getting ready to purchase it for the third time for another client soon. However, I am having trouble with the heading fonts appearing correctly in Chrome? They appear super anti-aliased – almost blurry compared to firefox. see here: http://170.a08.myftpupload.com/

Also, the font color for the nav in the header is appearing in like a washed out version of the font color I chose in the theme options until you mouse over it? In both browsers. And is their a way to expand the number of font choices available for the headings in theme options? I kind of thought the list would have been expanded by now. These are all a big gimmicky and heavy. I was looking for a nice thin font like source sans pro or something?

thanks!
