Yeah, I acknowledged my shame with this decision in the post. I did buy this $15 radio kit to "practice" soldering: https://www.amazon.com/gp/product/B004YHZE0G, but I've already somehow oxidized my solder iron's tip to the point that it won't heat the solder anymore. I would love a dummy's guide to soldering (YouTube or books) recommendation if you have one! (Although, I'm sure practice, practice, practice is going to be the top suggestion).
