The GCDC 3-axis accelerometer is used like a flash drive. Plug it in to a USB port and edit the configuration file for time and sample rate. Then unmount and collect data. The resulting files can be opened in Excel or other applications.
I am not as far along on the 9-DOF. The board is self contained you just need power and a way to get the data out of it. They provide a demonstration program you can load into the device and have a companion app to view the data.
Have you seen this thread activity-tracker-with-an-open-bluetooth it looks like they have done most of the work in the linked examples.
