I can tell that you will love hammock camping.
Setup can be very simple. We just get carried away here and let our imaginations run wild sometimes, just for the fun of it!
You are concerned about insulation, as you should be. But hammock insulation is simple if you picture a conventional sleeping bag cut in half, lengthwise, such that you end up with a top half and a bottom half. The top half lays on top of you, the top quilt, and the bottom half is suspended tightly up against the bottom of the hammock, the under quilt.
