I have tried brines and mixes like High Mountain and High Country and my personal taste is that I prefer the mixes verses the brines. But this is very subjective and I would encourage you to try several different mixes and brines to see what you like.
For sure you MUST have a jerky dryer or some type of homemade fan to pull the moisture out of the smoker.
Some people hang their jerky. But I don't like this especially in the #1/#2 because there isn't enough height to get the meat far enough away from the heating element. So I just lay my strips on my racks and periodically rotate the racks from top to bottom and front to back. I purchased the seafood racks from Smokin It, but there are other cheaper alternatives out there that have been discussed here.
I also use chips verses chunks because they start smoking at the lower temp that you use for jerky drying.
Let us know if you have any other questions.
I am getting excited for deer season too even though I didn't get drawn for a tag this year.
My son, brother, and Dad did get tags though and we always share our deer no matter who shoots them. So, hopefully we'll have plenty.
