I found the material in another comment. I only had time to listen to a few new tracks, from my phone speaker. So, maybe not the best way for me to hear them.
Live guitars- Honestly most anything will do. Eddie van Haken famously played some 30 way Amp, miced behind the giant wall of cabs his whole career. Once you mic it, it will become as loud as the venue can make it. I honestly switched to digital amps. Reliable, no one can kick the mic over, my signal is cleaner, less to move around. In live shows. No one, especially non musicians are going to care or notice. If you get a usable crunchy tone on 40 watts at low volumes. The venue can make it sound loud through the PA. So no worries there. But consider a line 6 helix. I used a mooer ge200 for practice and it's awesome. Does everything I need and mooer.
Recording - Get yourself a D. I. box. Passive works. Even 20$ ones. 8t makes the signal cleaner for digital amps to work with. Run into that then into your interface. Make sure gain never turns red on interface, never goes over - 6db in reaper. Ignite amps has some free amps that sound great the Emmisary is awesome. Find some free Impulse responses from OwnHammer or others. Try mixing the IRs together (Impulse response aka sound image of a speaker/mic combo) . Example. I typically use an IR of a 4x12 cab with a front mix and the 2nd IR is typically a room or back of cab mic. In Reaper eq high pass around 80hz low pass around 5000-7000hz will clean up and tighten up the tone.
In ear monitoring- My band uses a soundcraft Ui16. It's a digital mixer meaning I have to use a phone or tablet or laptop to adjust the settings on it. We run the drum mics, guitars(1 miced 1 digital pedal Amp), vocals, bass into the mixer. In the mixer you adjust your levels, Eq, compression, basic effects like you do in reaper. You can then route the modified signal to headphone amps, plug in your headphones and hear what's going on. You can route the unmodified signals to the front of house and they can adjust the sound to the venue. So you can hear perfectly what you want to hear, and the audience can hear what the sound guy wants. Plus, you can record the show while playing and now you got a mediocre live Mix.

It will help give you an idea of the rabbit holes you are about to enter.
Wording ads- This is a hard one for me as well. Keep it short and precise.
Looking for a metal vocalist Want to be a 2 man project. Songs are written need lyrics My music is thrash/black/Death inspired<<(a good word so you dont put yourself into some subgenre you don't want)
*I myself started this band with my drummer from my disappointment with the previous band we were in. I wanted to write new stuff and it was getting manipulated into something I didn't like at all. So I left. Not on bad terms I don't think. But I tell all our current members. If your not interested, go, no hard feelings, no animosity. I love all my members, but if they aren't musically interested. I don't want people to have to play music they don't like. But I've found myself a good group now. Since then we have changed a bunch of stuff about my song ideas. For the better. I had to learn to trust the other musicians. There's plenty of times people just go along with my ideas and they work. Other times they offer input and the change enhances the song. If it doesn't we don't do it. But I've had to write parts different so I could give the singer a break between parts or the complex drum pattern was clashing or taking away from the overall groove of the song. So, stay true to your ideas, but always be willing to try another idea until it works
*Funny enough I have Tinnitus very bad and my wife actually had the idea for the band name "Tinnitus Attack" while I was having a very bad attack one day, I could barely hear or see. Was odd.
