mail_cache_min_mail_count isn't related to single instance storage at all. I didn't really even remember that such a setting existed. I'm not sure if it's actually useful in any setups.. Maybe you were thinking about mail_attachment_min_size? Other than that, yeah, the mail_attachment_dir is really the only thing you need to set to enable SIS.
