Thank you for talking me through this! Yes I am using the new code and am impressed by how easy and slick it is.
I'd like to clarify my issue here:
I found that the Javascript that wasn't working most recently on my site, the AdSense, was due to the fact that it was in the post loop , and was registering it's Javascript and messing up the other ads, despite being excluded from the homepage via the theme and some Custom CSS. Tweaking the PHP so that the ads were single-post page exclusive fixed that up nicely.
It now looks like everything on the page is working, despite the fact that it throws JavaScript / JSon errors like a rapper in a strip club. (I got over most of these by forcing the Facebook Javascript to load in the header asychronously with some custom (non-plugin) code but they still showing up in the background in Chrome, etc.).
I guess this was a dumb thread to start because I'm just complaining at this point, being OCD about the errors while simultaneously not understanding JavaScript enough to understand why Chrome / Safari gets so angry at them has taken its toll ...lol.
