My 2p; I make and use virtually all my own kit for hanging;
3.3 m Pertex 4 hammocks. Single or double layer depending on whether I'm using a mat of some kind between the layers. I use an Exped 9lw Downmat for stupid cold conditions (Arctic winter trips) Whoopie slings, Dutch Whoopie hooks and 4 or 6ft tree straps depending on how big the trees are where I'm going. Very rarely do I use the detachable midge netting.
3.3m x 3.1m Tarp with doors. Centre panel pull outs. A homemade ally hook on one end and a Dutch flyz on the other end of my 12m Dyneema ridgeline.
Pertex shelled down underquilts- short ones for 3 season use or a full length for colder camps.
A down sleeping bag used as a quilt (feet in the footbox)or a dedicated down hammock top quilt.
I hang year round, often in the house too. The above setup, tweaked a little and in various guises and colours, has given me fantastic service abroad and at home in harsh conditions.
I'd recommend a DD frontline(as a noob hanger, you'll probably really appreciate the bug netting), a tarp with doors of some kind, 3m long will be fine and ideally an underquilt. CCF mats like a Karrimat are fine, cheap and very warm for their weight but need modding or doubling up to get the shoulder coverage because they aren't quite wide enough at 24". There is no substitute comfortwise for a decent underquilt.
The very best of all setups on the market IMO for quality and resale value is a Warbonnet Blackbird hammock, Hammock Gear Underquilts and Warbonnet or Hammock Gear Tarps, with Dutch titanium bits to rig it all up. Very much overkill for a starter though unless your quite flush.
