I'd agree with router before a drill press, miter saw, bandsaw, and a jointer. However, for simple furniture projects, I'd argue a planer is the second most important tool behind a table saw. You can use a planer with a sled for face jointing, and a table saw sled for edge jointing. Yes, you need a router for edge profiles, but not for dead simple tables and cabinets.
Exceptionally versatile tool, and necessary to take you to the next level, but not more important than a planer.
Windex to clean, let it dry for a bit, then a layer of gluestick has always worked for me, as long as the bed heats to 60°C for printing. The z offset has to be a bit different for PETG than PLA, which can be a bit tricky. I think (been a whole since I've printed PETG) it had to be a bit higher than PLA, so it wouldn't "squish" as much as PLA. Seemed a bit counterintuitive, but it solved most of my problems
