If you are looking at a hammock setup, I wouldn't go for what you have listed, it's pretty heavy and you will move on from that quickly. I just built a modular hammock setup that comes in just a little over 2lbs for $200. It uses no hardware, just a becket hitch to attach the straps to the continuous loop. Don't know the name of the knot I use to tie up the tarp, but many can be used.

Hammock $30: Wide Netless Hammock from Dutchwaregear with continuous loops and ridgeline

Tarp $80: Hexagon Siltarp from Amazon

Bugnet $57: Bottom entry bugnet from dutchwaregear

Suspension $25 UHMWPE Straps from dutchwaregear

The only additional things you need is an underquilt/pad and a quilt/sleeping bag.

If you are trying to sleep two people. I would get two hammocks, maybe a bigger tarp, and dutchwaregear offers a double bugnet. Sleeping two people in one hammock all night is not going to be comfy.
