With Captain Ed already helping out on Reaper I think I can help out some with the gear related question. I've been watching a ton of content on how to setup a beginner home studio and what gear is good to start with. First is to get an Audio Interface. The interface is where you plug in your mic/instrument input as well as having your output jacks for a pair of studio speakers and with some a headphone jack for your headphones. Focusrite's Scarlett series is incredibly popular, low priced, and well made. The Solo model has 1 mic input and one instrument only input so you can plug in a microphone for say vocals or an instrument as well as the strictly instrument only for a guitar/bass cable. They have a couple tiers above as well that have 2 Mic/Instrument jacks, 4 of those, and I believe an 8 input as well. Each tier getting more expensive of course. From there a mic or two is good to have if you want to record your own amplifier if it doesn't have it's own DI Out jack. The Shure SM57B is a studio standard cab mic that is never not seen in any decent studio. They're great mics and relatively cheap too! For vocals the Shure SM58 is another industry standard vocal mic good for live or studio situations. Another choice for vocal microphones is a Samson C01 which seem to be well reviewed too. Depending on your living situation whether you live in an apartment with rice paper for walls or you are renting/own a house will help you choose between headphones vs studio monitors. If you go with headphones the Audio Technica ATH M40x's or the M50x's are great headphones. For monitors I have heard great things about Kali Audio's LP Series. They're pretty cheap, are eq'd flat, and seem to be pretty sturdy! So to make a list of stuff that's a tad easier to read

And if your budget allows some good acoustic treatment!
These are of course just recommendations and I haven't personally used any of these before. I'm just recommending these after watching hours of videos over the last few months.
