Yours is a very impressive "starter shop". Very wise decisions.
If I were to round out the shop, I'd add a set of Woodpeckers squares (largest to smallest), Woodpeckers rulers (short and long), Starrett combination square set, and a Festool 1010 router to augment the monster 2200. I didn't see a drill press and I use mine all the time. I'd add a CXS and C15 drill. I'd buy some excellent ear muffs for noise abatement. I assume you have eye protection. I'd replace the non-Festool dust extractor if the one you have is noisy.
My wife and I have a "don't ask, don't tell" policy on her purchases and my purchases. If she does ask about one of my purchases, I tell her exactly what I bought and what I paid. I show the tool, or whatever, and explain in excruciating detail how it is used and why I needed it. We trust each other to use good financial judgement and we trust each other to be completely honest. And, yes, I do tell her if something she is wearing makes her look fat. I say "that dress doesn't do justice to your beautiful figure". She tell me "you're getting fat". Such is married life.
