Hi Lindsay;
Nothing comes to mind, seems like a combination of JS & CSS-related issues.
"really affecting the iPad primarily is seems in landscape mode" jumps out. I would first try to get things working on a desktop browser (Chrome or Firefox?) and once that's OK I'd look into the landscape-tablet problem (which is probably related to media-specific CSS).
Regarding the exclusions; are you sure about the capital Q in jQuery.js?
Hope this helps,
frank
