Nice looking dog. Start with basic obedience. Get him whistle trained to return and stop, best thing I ever did for my GSP.
I would start with a long check cord and tracking in an open area. Keep in mind that it's attention span is pretty short right now, but it will pick up things like a sponge. Try to make training fun.
Also, check out standing stone kennels on YouTube. A lot of bird hunting and training info there. They specialize in GSP training. Above all be patient as GSP can be stubborn.
As far as tracking goes, I can't be much help. I'm looking into it as well for my Malinois.
