Large backbone.js web app organization

I'm currently working on a large web app built on backbone.js and have been having a lot of issues with organization, "zombies," etc. so I've decided to do a major refactor of code. I've already written a bunch of helper functions for dealing with the "zombies"; however, I'd like to start from the very beginning and create a nice structure/organization to the code. I haven't found many great tutorials/examples on large-scale backbone.js organization so I've sort of started from scratch and would like to see if I can get some opinions on where I've begun.

jQuery code organization and performance
