This looks like another tool that could be useful to run against your code. I guess the purpose of tools like JSLint and jQuery Lint are to:
1. Highlight errors and incorrect usage. That's the obvious.
2. Produce consistent, standard, coding conventions so that other people can read and understand your code.
Whatever tool you do use, it should be easy to use and integrate as part of your development approach to your code.
These are just some initial thoughts.
Once you decide if JSLint is one tool you would like to use I would like to agree on which options you would like to check on (The good Parts) button on JSLint is a good start to conform to.
If so I would be happy to go through and produce a JSLint error free version of the code or as close as possible.
I guess working out how I would work on this and if you want it to be a parallel effort to the current code and left for your final review for inclusion or replacement of the current code.
Let me know your thoughts and how I can best help.
