Recommendations for my perfect hammock

[IndependentJo]

I live in North West Montana and will be living in the hammock for a year and a lot in the back country. No price boundaries.
Temps -30 F to 90 F.
I am 72" tall (6' 0") and weigh between 230 - 260 depending on the time of year and how good I am eating.
I have a lot of gear to carry.

Here is what I am looking for:

1. Comfort in all temps
2. Weatherproof - water / snow / baking in the sun
3. Light Weight - I know this will be difficult with the wide temp range.
4. Compression - Once again... difficult with temp range.
5. Least amount of parts possible.
6. If I absolutely had to I could set it up on the ground. Of course I would try my best to never have to do this.

Here is what I have been thinking:

1. Clark NX250
2. Whoopie Sling Suspension
3. Blizzard Survival Tube (there has got to be something similar but more durable than this thing?)
4. Underquilt - not sure what to do about this. Seems bulky.
5. Sleeping Bag - Wish I could use a full jacksrbetter style down body suite instead of lugging around a full sleeping bag.
6. Storage - I need the entire sleep system to compress down as much as possible. Maybe the size of a large sleeping bag. The backpack I will be using is a Gregory Baltoro 70 which as a volume of 4638 in³ / 76 L.

Tarp. Do I need one? I was hoping I could just sling something like the blizzard survival tube over the entire thing and be done with it. They are much more compact than a tarp and are still waterproof. If I can go without the tarp I need to think of how I will make it so that I don't collect too much snow. Maybe I could find a way to pitch the blizzard survival tube. I do not need to worry about keeping anything else besides my sleep system waterproof. I have everything else covered.

What would you go with in my situation?

Hope to see you guys on the trail!
