Working from home since 2007, I do keep my setup very simple: - good quality chair - single 27" monitor with adjustable arm (to level it with my eyes) - Microsoft Sculpt ergonomic keyboard and Logitech G603 mouse - mouse pad with wrist rest - audio interface (Focusrite Scarlett 2i4) and high-ish quality microphone (AKG) - Sennheiser open headphones (HD 518 I have for ages) and KRK studio monitors At the end the highest impact is having dedicated room with doors that close. Especially when kids are around.
