I use some version of Peak at work and can offer a little bit of insight, however not fully answer your question. To track out a concert after all the fades/normalizing etc, I go (apple button)+M at the very start of the file, this places a marker. Then I put one of these in right before each song or wherever I want a track. Then at the very end of the file put another in. Then Edit>Select All, then find "Convert Markers to Regions" not sure which tab this is under. This takes the markers and makes them into regions that can be burned onto a CD. If you leave them as markers and try to burn them onto a cd it's just a data cd, no audio. We never have to save the individual files so I can't tell you how to do that, however it should just be as simple as after the markers just doing some variation of a save. Good luck.
