Basic obedience applies to all dogs, all breeds, and basic gundog training applies to all gundogs.
You need to teach your setters to walk to heel on and off lead, sit to flush/whistle/command, be 100% instant on recall (except if they are hard on sett, which you would notice from keeping an eye on where they are)
Some dogs need to be taught how to quarter but in general that is instinct (using the wind) The setting is instinct.
You could try joining one of the Setter Clubs, or search for setter training on youtube
Good luck
