I think most would replace all of the wax/paper caps and the electrolytics. The resistors typically tend to be within spec. I would measure them before replacement. Spec would be +/- 20% of value noted by the color code on the resistor. Check value with the one on the diagram as sometimes it may have had a repair that a different value was used. When measuring the resistance of a resistor that is in circuit make sure that it doesn't have a cap in parallel with it. If you do it won't be the correct value of that resistor. Since you are go to be replacing the paper caps it's a good time to measure the resistors.
Wouldn't worry too much about the transformers rf, if, power, and output. They typically don't change value. Can be checked for dc resistance (continuity) with an ohm meter. Most of them can be found as new replacement parts except for the rf coils/transformers. Sometimes you can repair a bad one (open winding) if your lucky.

figure out what all those squiggly meant.
