Alex,
Being new to ArchiCAD it would be a good idea to get to know the basic tools before you get to the Add-Ons.
Yes there are some great add-ons there, but by default I don't use them if I can get the job done with the basic -out of the box- ArchiCAD.
As for the specific questions: GS MEP Add-on doesn't have cables, I don't know of any other software that does. It's commonly assumed the cables will run in the pipes/ Cable trays or ladders. CADimage's add-on is more documentation oriented.- (2D)
check the ArchiCAD Youtube channel, there are great tutorials there. And the online help.
