Chris - In my experience, the core audio setting are not important for 
Jack OSX, however using the built-in audio since Leopard on an apple 
laptop with Ardour is a huge mess.  Save yourself the headache and but a 
firewire or USB interface.

I have copied many, many, many regions into a single playlist (track) 
and never had any problems.  Make sure your region pastes are active and 
there is not gain automation working.
