AFCI Circuit Testing ??

Good Morning,
I am not sure my Title is correct, so please bare with me..
I have a house built in 2010 and after having the AFCI Circuit Breaker for the Master Bedroom and Master Bath trip multiple times (same one), I put an amp probe on the wire and found the 20amp breaker actually had a little over 27 amps on it (with everything turned on, including the 2 exhaust fans). It appears the elect. ran the lighting and receptacle on the same circuit. I need to install another AFCI breaker and split the circuit. Installation of the breaker for me is a given, my question is: Without tearing into the walls to follow the wiring circuit, is there another way of creating a wiring diagram with a Fluke meter, tone generator or another device.

Turn off the breaker to fine what is all on that circuit (dead = on the circuit ) A circuit tracer will do the same thing, but with less reliable results.

The trick is finding a way to get another circuit from the panel to split up the circuit. Do you have an unfinished attic, crawl space, or basement which you can fish from?
