Great to have you with us! I also found ground camping to be very hard on the back. My hammock is so much more comfortable.
I know the feeling at the start. The forums can be a bit of an overload at first, with all the great ideas, techniques and info. That's partially what's so awesome about it all is the huge variety of different approaches that work.
But it can be kept really simple at the start as well. During good weather I enjoyed hanging in my gathered end hammock I sewed myself with only some ratchet strap webbing for suspension. It gets more complicated as you get into wet and colder weather. I'm also really into the DIY and have made almost everything I'm using now.
If you haven't see any yet, check out the series of videos by Shug, which are crazy funny and hugely informative.
