xmlhttprequest

I rather enjoy adding practical eye-candy to the networking community I've been developing but as things start to stack up I worry about load times.

Is it truly faster to have users load (a hopefully cached) copy of jquery from Google's repositories?
Does using jQuery for AJAX calls improve/reduce efficiency over basic javascript xmlHTTP requests?
Is there a practical way to cut down the number of included scripts? For example, I include jQuery and jQuery UI from google, table sorter, and a growl plug-in.
