Android 4.2 is FP1, Android 4.4 “just” available unofficially. Only Android 5.1 is running on Fairphone 2.
Preinstalled Apps are per se system apps and can’t be deleted or updated by the user.
If you go to Settings > Apps > All you can go through all Apps and view their permissions.
All code of apps included in the FP OSOS build is probably found here: http://code.fairphone.com/
AFAIK that only excludes GAPPS.
