The power wire needs to be staggered but how is that accomplished?
By soldering a wire to the power and ground to intermediate points in the strip. It is the PCB tracks that are thin and cause excessive voltage drop on long runs due to the resistance of the PCB tracks. You are in effect shorting out these resistive tracks with these wires.

What about the main power supply? Is there one that has multiple outputs?

Power supply options?

Or maybe a quick sketch or picture of an example of how it would be wired up?
(I'm very good at soldering etc so I can easily DIY it but just needed to see an example)

No you don't need them just one output and chain the wires.

Connect the ground to the start of the strip and also connect the ground at the start of the strip to the strip 100 LEDs or so further on. Connect this point to 200 LEDs in and so on down the strip.
Do the same for the 5V.

Ah I see. So the ground and power are just spaced intermittently along the length of the full strip. So it's distributed along the length.

Yes that is it.
