How to Connect GPS, Accelerometer And Encoder in Fez Panda II

hello, excuse my English, I’m from Chile.
I am a former programmer. Net and I started in this new world of embedded electronics products such as Fez.

I purchased the product Fez Panda II and I have the need to use a GPS, an encoder and an accelerometer to capture the roughness of a road from a moving vehicle.

This is the encoder that intend to use
