This appears to answer my original question, but I'm still trying to get it to work correctly:
As for page load times, I tested using Firebug and loads.in. It seems that the slowdown is a result of the AdSense scripts. Obviously, we can't remove them, so I'm not aware of any way to fix that particular problem.
The Analytics script doesn't have much of an impact. That's probably because we're using the asynchronous code. Nothing would be gained by changing its location. More on that here:
We already use a Google Translate front end that doesn't load most of the script until someone mouses over it. And the initial script is at the bottom of the page. We've stopped using DFP for Publishers scripts in favor of placing the ad scripts directly on the page, because they seem to load faster that way.
Any other thoughts you might have on improving page speed are welcome. I appreciate your time and effort.
