I don't think you need to read anything, since you have already understood everything you need to know. I think I remember your libraries a bit. Unfortunately you will have to change your code so that it does not call lists as functions any more. And - unless you redefine `backquote' - something like `(my-cool-new-lambda ...) with whatever tricky definition of `my-cool-new-lambda' will always return a list and thus be not `funcall'able. So if you need to construct lambda expressions using backquote - AFAIR that's what your code does - it's unavoidable to add some wrapper that `eval's the constructed lambda expression, like `eval', before you have a valid function value.
