Then loosen the rear camshaft pulley and do the timing procedure by rotating that pulley which then rotates the IP but not the cam? I hope that makes sense but lmk if it doesn't.

Almost. Rotate the rear camshaft pulley which (via the rear belt) rotates the IP pulley. The IP body stays stationary. Hence no need to loosen the injector hardlines at the distribution head. And no need to remove the IP or its pulley or other associated items.

You are correct that the camshaft itself stays stationary, as does the rest of the engine internal rotating parts.

What is important to understand about the notches on the IP pulley, IP and IP bracket?

The notch on the IP bracket is not important for the timing procedure. In fact, many of us prefer to have the IP mounted rotated further outward from the engine to make future access to the rear GPs easier.

However: The notch on the IP pulley and the notch on the IP are important to the timing procedure. When they line up (can ignore the notch on the bracket) that should indicate start of injection event for injector #1. But it is not high precision enough for accurately setting the timing, it is just a rough visual. That is why you use the dial indicator, which is a more precise instrument than coarse notches in metal.
