Excel 2007 - Auto Populate fields based on Cell Entry

Attached is a spreadsheet with notes.

Selections made by Department Heads on this spreadsheet are used to setup an employee's access to server data.  I'd like to make their job easier by auto-populating checkboxes based on an employee's status.  

For instance, a Service Technician's access to data would be different than a Service Manager's access to data.  I'd like the Department Head to simply choose either the Service Technician checkbox or the Service Manager checkbox and have the proper checkboxes for access automatically get checked.

Employment categories are listed on the spreadsheet along with more notes concerning what I'm trying to accomplish.

I just don't know the best method to do so.  "IF" statements look like they'd get too complicated to use.
