( some of these I beleive are the mutliple .woff custom fonts you are using)
also you are using a lot of individual images for things like navigation, It may be time to look at using css sprites for some of that.
Also since you are using several external sources for things like custom fonts, you are hobbled by the download speed of the servers you are pulling those external files from.
how did I get this much info? I used Firefox with the Firebug and Yslow extensions, very very useful
