Rick,
Also FYI in case you aren't already using or aware of TI-RTOS, you might want to take a look at it: http://www.ti.com/tool/ti-rtos
It combines SYS/BIOS with additional middleware components like USB stacks, device drivers etc.
There are some examples included with TI-RTOS that use both SYS/BIOS and Tivaware which could be a good reference and starting point for you to build upon.
After you download and install TI-RTOS make sure to restart CCS and enable the product when it is discovered by CCS. You should then be able to go into Resource Explorer (View->TI Resource Explorer) and take a look at the examples under ARM->Tiva C Series.
Hope that helps.
