I found out why I was having a problem with the pip boy. Mo2 was not carrying the original saves from when I initialized the game saves and went to play the game to initialize the game ini files (found in c drive User Documents\my games\fallout3). Default Profile in MO2 had no saved files. Therefore when I created a new Profile I left the "Use Profile-specific Save Games" un-ticked and "use profile-specific game INI files" un-ticked as well. By doing this, the new profile loaded up the original save files from the c drive User Documents folder. Thus, can continue save.
But which mods from Kelymch Mod Guide not to use is still trial and error.
