Alright. I took a stab at modifying the post using some information I found in the generic plasma engraver post that ships with Sheetcam. What I did was add in some "if" statements checking if zAxis = true or false. There were a couple of areas for penUp and penDown where I didn't exactly know if I needed to do anything, so I didn't. Anyhow I ran a test program through with the standard MPC1000 - Sciber post and it was full of zAxis movements. I then ran the same job through my modified post and the scribe process had zero zAxis movements. Once I got to a cut routine, the zAxis movements came back. I accomplished this on the toolchange function by specifying zAxis = false for tools over 99 and zAxis = true for anything else.
I ran the table with my scriber air supply off and my plasma cutter off, with a tight grip on my Xbox 360 controller to stop the job if something went haywire. It ran through the engraving function MUCH MUCH faster due to the Zaxis movements being eliminated. Once it got to the cut portion the torch came down, did it's touchoff and retracted to pierce height. Since the plasma didn't fire the program hung up there, but it seems at first pass it is doing what I want. I'm a newbie to this though, so I'm going to include my modified post here and hope someone can validate if I did it right or if I need further edits.
