For the most part, resistors may be tested in circuit. There are some instances where one end needs to be disconnected, but not always. If not sure, disconnect one end.
Capacitors, assuming your multimeter has a capacitance measurement feature, should be tested out of circuit.
I can tell you now that all of the paper capacitors in that set need to be replaced. They do not survive well over the decades and if not bad now, will go bad shortly after the set is put back into use.
Rule of thumb: Replace ALL paper and electrolytic capacitors. Replace resistors if not within 20% of rated values.
If you are in northern Illinois, you're in luck. The Antique Radio Club of Illinois is a large, well established group and they host one of the oldest, most respected, and best attended swap meets in the country each August - Radiofest. They also hold other meets throughout the year.
