Thanks very much for taking the time to look further into this and relaying the information above. I'm comfortable running commands in Terminal, but I have a concern about both those commands. There are several English language files (eg:Australian/Canadian....etc) and those should not be removed either - so I've read on (mostly unhelpful) Mac sites, except in unanimously cautioning against removing anything PPC, esp architectures.
Comment please...and thank you.

Also, I use EasyFinder, which is very thorough. I wonder if I could safely use EF to remove the remaining foreign language files safely? Running it before and then after using Monolingual revealed the removal of most .lproj files, but it does show a few thousand left (German/French/Japanese).
Comment please...and thank you.
Again, I'm really very grateful for your input and interest in helping me out -
very grateful.
