As far as the texture maps go, if Poser is asking for a map, then there must be a reference to that map somewhere in one of your files (or in a third party file that one of your files is calling, though that seems unlikely). There are other types of map besides texture maps, so to be sure there are no map calls in your files, you need to search for any and all occurrences of these text strings:

textureMap
bumpMap
reflectionMap
transparencyMap

"Master Parameter dials that did absolutely nothing even after the INJections". It's hard to diagnose what is causing that problem without actually seeing the files in question. It's most likely one of two things. Either the deltas are missing from the slave channels, or the name of the master channel does not match the name pointed to in the slaving code. Another thing that can cause problems is if the 'figure number' (:#) in slaving code in a pz2 does not match the figure number in the cr2. The remedy for this is to leave the figure number out of any slaving code in a pz2 (but NOT in a cr2). Also to make your cr2 more compatible with DAZ pz2 files, you should insure the figure number in the cr2 is ":1".
