Welcome from East Texas! There's a bunch of information on the site, and plenty to sift through. I don't think the learning curve is that big to be honest. I started out just using the same sticks I used for my hang-on stand, and added the saddle and a platform. After a couple seasons I started to change things up and try new things. I always practiced in the backyard to get comfortable with things before heading out into the woods. I'd rather get the awkwardness out of the way, which tends to be noisy, before getting out in the dark and clanking my way up a tree.
Have fun with it, and remember that each person does it differently. Don't be afraid to try new things, but also don't be afraid t stick with something if it feels comfortable either.
Be safe and have fun!
