I did exactly what you did. Started with the Grand Tunk ultralight, then upgraded to a Yukon Double.
The Grand trunk came with kinda lame hooks at the ends to attach the hammock to a suspension system. I upgraded them to Neutrino carabiners ($8 each on amazon). Super light, strong, and easy to use. I used them with the Grand trunk and transferred them over to the Yukon later.
You'll need a suspension system. You picked the atlas straps (same as me). You can't go wrong with them.
Technically that's all you NEED to hammock.
Other things, like the bugnet are a good idea. I just use bug spray myself, works ok for me but my area isn't that bug infested usually.
Under insulation, you can just start off with a "blue pad" from walmart. It's a blue roll up camping mat that's made of foam. I think it's $8. Will work under you to prevent cold butt syndrome. You body weight will compress your sleeping bag so you'll want other insulaton under you.
You'll want a tarp if there's chance of rain. I bought a Base Tube Tarp 1.0 off amazon, like $20ish. Works just fine, especially if it's not a hurricane.
All in, with the hammock, atlas straps, blue pad, and tarp. You'd be about $75. Which is about the cost of an ENO Doublenest, and half the cost of a warbonnet blackbird. You can always upgrade your stuff slowly later.
