All very good questions,
I don't claim to be any kind of pro at all, but I will tell you about what has worked for me in the past. Keep in mind no matter what advice you get, it always boils down to what works best for you. OK, with that said, here we go.
Practice Practice practice- There is no max or minimums. I start at 15 or 20 yards and shoot until I am comfortable with the consistency of my shots. I usually shoot three arrows per round. This gives my arm more time to rest while I go pull the arrows out. I will not move to a farther distance unitl I can put all 3 arrows in the kill ZONE consistently. If my arm or shoulder gets tired. I stop. Usually I notice my grouping getting worse before I noticed the muscle fatigue. The big part is making sure you are doing the exact same thing every shot, such as, anchor point, breathing, pin alignment, and grip to name a few.
Workout, I have a regular work out schedule at a gym, but I know guys on these forums talk alot about the rubber stretchy tube thingy for a good bow workout. I can't remember the name of it, I'm sure one of the other guys on here will let you know the name of it.
For maximum distance, that's gonna depend on you. If you don't feel comfortable shooting past 30 yards, then don't. Just make sure if you set up ground blinds or start using treestands that your shooting lanes are setup for your max distance. IE, 30 yard long shooting lanes.
Stances, I practice shooting from a seated and standing position as well as from a treestand. Since these are the postions I will most likely use in hunting situation, that's what I practice.
Targets- For the best realizm you would want to shoot at a full sized 3-D target. I know there are alot of very pricey targets out there. Another thing you can try is the life sized picture targets or burlap targets you can just hang over the front of your hay bales. They are much cheaper.
Broadheads or field points- I recommend you use the practice heads for your broadheads if you use fixed blades. It just makes sense. If that's what you are gonna take in the field then that is what you should practice with.
Treestand angles- This one is a pretty lengthy discussion in itself. Basically, the steeper the angle of shot, the flatter your arrow is gonna travel. The best way to see what everyone tells you about it is to setup a treestand in your yard and shoot at a target from differnt angles from 10 all the way out to your max range. From doing that you will be able to tell how your shot is changed from shooting on level ground.
Hope this helps you out, they are all tried and true methods for me. I enjoy every minute I get with a bow in my hand. Another important part is, HAVE FUN!!!
