Actually the fingerprint info is to identify if the phone is a normal unrooted or the developer phone ie ADP1 and then hide copy protected apps for ADP1. The reason for this is that on the ADP1, root access is enabled by default and hence it will be possible to copy any app from the phone out.
The network operator code is to allow operators to block out certain types of programs if they want google to do so. So by spoofing the code, you can access apps that your provider doesn't like... like say tethering apps on at&t.
Oh and the operator code allows the market to decide if you can see paid apps.
