Work on prey drive - tug toys are great
Start ASAP
Don't count on your GSD "pointing" - but retrieving should be fine
GSDs are not "natural" hunting dogs, but with the right foundation, should be fine for at least retrieving your catch.
If you decide to run with this, consider a Dogtra training collar. They are expensive (+/- $200) but NICE. Big range, finite correction controls, weather resistant, and has a vibrate/page feature as well as the shock. Remote training collars are in many opinions, necessary for training any dog to hunt as you have to send them out further than you can control with a leash.
Run some google searches on hunting dog training.
Prey drive training will get her to do something once she is "right at it". Unfortunately prey drive varies depending on the individual dog, not just the breed. GSD are used for sport (schutzhund/french ring) and prey drive is a good part of those sports, it is a matter of honing the drive and encouraging it.
