So you have some options, and ultimately it comes down to future ability.

Starting out, you can buy a SM58 for cheap, and it'll have pretty nice quality. It outputs mic level signal though, so it will need amped by something, which is where your choices come in.

If you're looking to keep it cheap, you can pick up an audio interface to get the mic up to a reasonable level and into your computer. Something like this. This setup will run you ~$200 in total (mic and interface), but will limit what you can do with the equipment you purchased.

If you're willing to shell out just an additional $100, you can grab a mixer like you said. This would be my recommendation. It gives you 4 mono inputs and 2 stereo inputs, opposed to the 2 mono inputs the interface above provides. It's also a fully fledged board, so you can use it for more than just getting audio from your mic into your computer. Its USB interface is pretty handy, too. It'll send 4 channels to your computer and your computer can input 2 stereo channels back to the board.

Initially I only used my board for getting my mic into my computer, but I've ended up using it for mic and guitar input into my computer, as well as computer audio & DAW output to my monitors.

The board's pretty handy, but if you don't need it there's not much reason to buy it. If you're only ever going to use one channel to get your mic into your computer, you're probably better off with the interface, as setting up the board can take some time. Plus, if you don't have studio monitors / speakers that take analog input, the board isn't going to help you in getting signal to them.

So it pretty much depends on what you need, and if you plan on expanding or not. Rule of thumb, however, is to plan ahead so you don't end up spending more buying something you could have bought earlier. And if you plan on getting serious, you're going to want to pick up some studio monitors.

But again, if you're just going to be recording some covers every now and then in your room and not much else, I'd recommend going the interface route opposed to the full on mixer route.

Shure mics are the way to go. Shure SM57 is an affordable and great way to start recording screams. In terms of other stuff, a mixer, a good program (i.e. Pro Tools) A pop filter sometimes is good but I often find it's better without one. When recording make sure to stand maybe 6-12 inches from the mic. It always kinda depends on how loud you are but generally if you're doing false chords it won't be all that loud so you can stand closer.

besides warming up and drinking water? well, first of all, drinking even more water. 🤷‍♀️

this stuff is also great for keeping your throat lubricated - don't rely on it as a crutch, but it can help protect you in conjunction with hydrating: https://smile.amazon.com/dp/B000Q3BZQE/ref=cm_sw_r_cp_apa_i_wyGUCbSFF97C8
it tastes kinda gross but also kinda good? lol

technique-wise: i know you know, but the better your breathing, the less likely you are to put any undue stress on your throat. also, keep everything loose! to minimize tension, before you start, try stretching your neck, massaging your jaw, shaking your head around, etc. sounds silly, but keeping everything relaxed will not only protect you from actually hurting yourself, but will also decrease the amount of total energy you're using to get the sounds you want. personally i haven't had a problem with extra tension when i scream, but this helps me soooo much with regular singing.

A device that turns the microphone XLR signal into the computer USB plugin. Here's one, but there are cheaper options https://www.amazon.com/gp/aw/d/B005OZE9SA/ref=mh_s9_acsd_simh_boEu3_c_x_1_w?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=mobile-hybrid-3&pf_rd_r=2CPG8HCA6JDFF2NFJ3JZ&pf_rd_t=30901&pf_rd_p=ee07def2-2960-57dd-bab4-05e4ca602ed0&pf_rd_i=11973691
