I use the 360 version of this and would definitely recommend it

Camping Hammock with Mosquito Net, 11 ft, Ultralight Hammock Tent with Bug Netting, Straps, Carabiners, Structural UHMWPE Ridgeline, Ripstop Nylon (Green 180 Half Zipper) https://www.amazon.com/dp/B08YY9GDCH/ref=cm_sw_r_apan_i_5AC0Q2NXKCRKM2KGGA43

Though I use a different suspension system I would consider the one it comes with adequate.

Tons of great rain flys out there, a regular rectangular tarp is a cheap easy way to get started especially if you don't need something super light or compact.

I use an older Eno ember 2 underquilt, I'd probably recommend a different one though it works.

You can just use a regular sleeping bag instead of a top quiltt
