I don't know about the ASP.NET part but the only way I stayed sane using jQuery a mid sized project was using patterns, mainly the module pattern to encapsulate functionality.
I would start here: toddmotto.com/mastering-the-module...
The ever great Addy Osmani wrote an entire book about patterns in JS (I haven't read it to be honest :D): addyosmani.com/resources/essential...
Hope this helps!
The main question is if there's anything blocking you on progressively upgrading the jQuery stack or if you're stuck on not having any bundlers
