Hey,
Sounds like your on the right track.
#2s out of the that turkey gun would probably do well....
As for your calls, are you mouth calling or electronic? If your using mouth calls, there are a couple that pretty much do all you will ever need. If you want to know, I will PM you with them. Easy to use and very versitle. I got several mouth calls and a Western River Predation (mp3) and a JS Cassett call. But, the Predation and two particular hand calls seem to get the nod. One even works for an elk bugle, as well as howls, barks and distress sounds.
Good Luck
Andy
