Hey Sam,
The first error is most likely due to attempting to load an array of helpers via $this->load->helper().
ME allows you to use the $autoload['helper'] class variable to do this more easily and only supports loading single helpers via $this->load.
The second and third errors are a bug in modules::run, which I will fix and then send an update.
EDIT:
If the controller is not specified it will fail as you suggest. The other test to determine the method is correct.
Setting index.php error_reporting(E_ALL ^E_NOTICE) will suppress these errors in the meantime.
