Tools you will need... Like what bombastinator said, you'll need something to cut wire. For stapled claptons, I recommend wire cutters, and toenail cutters like he said. For just regular wire, I actually prefer fingernail cutters since they cut close to the posts. If you're looking to buy wire cutters, make sure you get one that has a singe sided blade. Ones that have a double sided blade tend to leave a bit of the wire sticking out of the post which can be annoying when you're building. Scissors. make sure they're sharp. I specifically have a sharp pair just for the cotton cutting, since dull scissors may cut paper fine, but they don't cut cotton well. You'll need some sort of post that fits in the middle of the coil for positioning it once it's screwed in. Usually the end of a drill bit (not the sharp edge) works fine.. just make sure you clean it first thoroughly. They make special rods, for that, or a coil building kit, but since you already bought premade coils, you don't need a kit. And an Ohm meter is preferred. If you don't have one, then your Charon should work fine.
Now, one thing to note, you have .3 ohm coil, which is fine for the pharoh. But if you ever decide to get a two coil atomizer, you'll want to look for a higher ohm coil, since you will be halving the resistance. But for the pharoh, you should be good to go.
I think you have a great setup there. I think the setup you have is perfect for beginning RTA's. The pharoh is a good atomizer to learn how to build RTA's I can tell you've done some research. The best thing to do is to dive down in and start using that video he provided. How much cotton to use takes some practice, but use your best judgement to begin with... if it dry hits... use less cotton, if it floods, use more. Just try not to pack the cotton tight. Usually when you seperate it, try not to pinch it together too much.. just enough to shape it round.
