It's most likely not your plugs. Anything between .018-.025 is safe under boost from misfires and good for every day use. If the car idles rough you would want to make the gap wider, closer to the .025 mark.
Yes P/T fuel and P/T ignition is what you want to adjust, the key here is to keep everything as smooth as possible rather than making it choppy, simply try changing the values by small amounts.
The problem you are having with the tabs is a known WAR software issue that is being address in the new version, the new version is going to be released soon. Until then click on the tab you want to save to, open the map and write it to the chip when ready. The tabs always stay the same as does the TCM.
Neither the DME or the diagnostic tools are aware of the WAR chip replacing the original EPROM, therefore I will have a hard time trying to narrow this problem down for you. It might have something to do with using a DME from a different car? Again its hard to say. If you are simply trying to retrieve the check engine light codes, the stomp test should work fine.
The last question you asked is a very good one, it is something I am working on myself as I am trying to get tracing to work. This feature allows to see exactly which values the DME is accessing at a specific time.
Here is a quick example of what it looks like.

I think the DME looks at the RPM and TPS and if its above aprox 2000RPM it is in the P/T map, anything below aprox 2000RPM and it goes to the idle fuel map.
