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

although not as connecting to Fez Panda II. Hopefully someone can help me with this.

We also need recommendation for the purchase of GPS and accelerometer, I can use?, What do you recommend?

Many thanks for your help.
