Letterbeacon,
What I did was go through the schematic and count how many standalone connections were required. Obviously a cathode resistor going from the valve base to the earth Busbar does not need one but a plate resistor to HT does. I then fitted the required number of tag strips plus some spares. I have found that making a practical copy of a symmetrical schematic works best. Orient the valve bases so that things like coupling caps will be the same length. I go by the old engineering maxim "if it looks right, it is right". components should not be too close together, too fiddly to assemble, or too far apart, more prone to pick up stray signals or inductance.
I usually make a sketch of the proposed layout first, then I physically place them to see if it works in practice. Its worth taking time over this as it can save a lot of grief later, we usually only get one shot at these amps so it has to be right first time.
Incidently, the 4.7k resistors on the 6SK7's are to provide a 4.7k output resistance to give sufficient bass to the interstage, it cuts the gain a lot but there is more than enough gain to spare. I don't think the interstage is necessary myself, but it was common practice to use them at the time; 1950.
One other potential problem area is the feedback string, this must be kept as short as possible to avoid oscillation, its got several hundred volts of ac on it so you could easily induce it into a sensitive part of the circuit through stray inductance/capacitance.
