There are a few ways to do this, but the easiest way is to chop the long track into smaller tracks and then load them into your CD burner app. I use different programs depending on what my final goal is. If you are going to fix overall levels and do a quick bit of compression, do to to the whole track, then clip out the individual tracks (copy, paste to new file), fix heads and tails, and burn.
If you can use an editor that supports regions, then you can just drop region markers between tracks. If the app supports regions then it will probably allow you to at least save as a SDII file or a disc image, and either will load to a program like Toast with the track splits intact.
My usual choice of app for this is DSP Quattro. I can do the entire process from editing, effects, track markers, and burning, all without leaving the app. DSPQ is having a few growing pains in the transition to Intel and Leopard, but it works great.
I also have Wave Editor, but have not done enough to be comfortable with its work flow.
Look around in the GB helpfile for track markers and see if you can do that. I have never tried, but you might be able to place markers and burn right from GB, or export to iTunes and burn from there.
