Depends on your state on all your questions. Here we can use a stand, but can't use rifles. I am not a huge blind guy, but they do work. Get you one that can give you room if you need a blind. If you are going to sit you might as well be comfy.
Also are you asking for fall or spring turkey? The way you approach the hunt is different.
Calls- start with a good/easy box call, this is the longer thin call with the moving lid. A very easy call is the Primo Box Cutter. Pot call (peg and pot) is a friction call that is about 3" or so. There are good commercial calls, but you can get a custom call for about the same price as a commercial (PM me for specifics). I like slate over glass.
Mouth calls are the toughest and you should start now if you want to use these. They will make you gag a little, but start trying to have them in more each day. Start by trying to make any sound- this call fits in the roof of the mouth. Quaker Boy makes a foam fit that is good, HS also and Primo has a sonic dome call that helps with starting. Get a 2 reed call to start. PM with any other questions.
