all the above will come with experience mate weather it is with some body hlping you or just getting out there doing it your self.
spotting is quite easy rabbits (droppings on the floor of runs through the grass or acctually finding a warren ect) birds (look for shapes in the trees or movement or disturbace this will have to come with experience and a keen eye tho and make sure you identify you quarry. you dont want to be killing nonlegal quarry) hope this helps a little bit and good luck
