Get a decent set of decoys consisting of 2 hens and a Jake for starters......some guys opt for a tom decoy with a couple hens, but sometimes toms that aren't dominant will shy away from a mature tom decoy, where he will almost always think he can kick a jake's ass.
Don't go overboard on calls to start out with, get something relatively simple to use such as a box call and a push button type call. Primos makes some good ones and there are a lot of other brands out there that work good also. Practice with them before the season comes in. Those are the type of calls I have used for 20 years with the most results. Some guys will also use slate calls and mouth calls, but there is a larger learning curve with those IMO.
As far as scouting goes you can look for scratching in the woods, but the best way to locate birds is to physically see them somewhere close to season or during season. Turks move around quite a bit in the spring, breaking up from winter flocks....where you see them now is probably not where they will be the 3rd week of April.
If you have a blind don't be afraid to use it during turkey season....Turkeys don't associate a blind with danger like deer do. I have had birds almost join me in the blind and seem clueless to what a blind is, even after it was set up just the day before.
Use plenty of gun when shooting turks and don't scrimp on good ammo. Buy the best shooting ammo you can afford, because you will only get a couple shots per season and a box of shells should last several seasons.
If I can think of some other things I will let you know.
