Great post J-bird
I will add: don't have a particular brand in mind when you go to the shop. SHOOT ALL OF EM and then choose. I had a particular brand in mind when I went to Cabelas, and then ended up with something completely different. It fit me the best, and it had the cleanest trigger. I didn't like the trigger assembly and pull on the brand I thought I wanted.
Make sure you shoot your broadheads at a target too... don't assume they fly the same as field points. I am shooting muzzys because I like fixed blades and I can shoot the same broadheads out of my compound. Took a bit of sighting in to get them shooting correctly, and they shoot good out to 40. At 50 though, they start getting squirrely. With so much power planing can be an issue with some broadheads, and even some mechanicals.
Shooting sticks are not a bad idea, as J-bird said they can be heavy and unbalanced
I also highly recommend a rope cocker or pulley, makes cocking much easier AND it will be done consistently every time, which leads to better precision and accuracy
