Cable pulls are from the device to the headend. This allows you to set up multiple stands and pull multiple rooms at the same time.

I use the same type of system for labeling. We use Brady laser printer labels. In our design process, we assign IDs to individual cables when we create the wire-pull lists. These designations then make their way into the wiring schematics later on down the line. We start our numbering from X000 and work our way up. Every cable in the system has a completely unique ID.

Our numbering convention is as follows:

RR_SS000 where R = Room, S = Signal, 000 = unique number, so for instance Great Room Plasma video signal is

GR_RGB001

Great Room Plasma 232 is
GR_C001
