Hi Ethan. Here are some of the Essentials that I use every time I make/mount a Coils.
Atomizer Stand: I like SS because it is Heavy. And it doesn't want to Tip Over as much as say Aluminum. Also, being thread on one side and Thru Hole on the other is Nice.

Flush Cut Diagonal Pliers: You are going to need a way to cut the coil wire Very Close to the Atomizer Screws or Posts. So whatever you decide on, make sure they are "Flush Cut". I use these and they work Great.

Coil Jig: Not absolutely necessary, because you can Wrap a Wire around just about anything round. But very handy to have none the less. I use the 2mm Mandrel to adjust the Coil as much as I use the 3mm to Hold or Make a Coil. I also keep Odds n' End under the Coil Jig like Allen Keys or a pair of Nail Tweezers.

Scissors for Cotton: I have Tried a Lot of Scissors for cutting Cotton. And, IMO, these Micro Serrated Surgical Scissors are the Best.

Ceramic Tweezers: I don't uses these that often. But if you need to Holed/Adjust/Jostle a Hot or Dry Burning coil, they are kinda a must. The bottom Combo Tool is can come in handy to Grip the Atomizer Deck on a Stuck RTA.
Ceramic is Fragile. And the Tips are Easily Broken. So use/store them gently. But what ever you do, Do Not Ever Touch a Coil with Anything Metal while there is Voltage Going thu the Coil.

These Storage Boxes are Great for keeping Cotton Pads or whatever in. And if you are going to do a FT Order anyway, I'd throw One or Two on the order just for the Heck of it.

As for Wire and Cotton? That is kinda an Individual Choice. I think Pad Cotton is Easier to start of with. Because it is Easy to Gauge how much cotton you have by the Width of the Strip you cut. That, And I don't think Bulk Cotton or Rayon performs all that much better. Buy Opinions Vary.
Another thing. Not sure how good your Eyes are while doing Close-Up Work? But with mine, these are a Must. As with Anything e-Bay, do some Research on your seller. The Listing below is just for Reference.

The LED Light really doesn't work all that well. But the Flip Up type of Lens is Very Handy for switching from a Build to looking at a Computer Screen/YouTube Vid. Or for when you get up to get something from another room.
