In order to add the "Department" to the subject line of emails coming from the Contact Us page, you will need to edit the help_contactus_subj.tpl file. The file location is /common_files/mail/help_contactus_subj.tpl.

Find:
{config_load file="$skin_config"}{$config.Company.company_name} : {$lng.eml_contact_us_subj}

And change to:
{config_load file="$skin_config"}{$config.Company.company_name} - {$contact.department}: {$lng.eml_contact_us_subj}

That's it.

I am still very interested in finding a solution to direct the email to the separate email addresses of each department. If anyone has some direction on where I might start, suggestion, or solution, my ears are wide open.

Thanks for reading.
