I think your questions have been answered but I would be concerned about seeing some receipts from the rebuild and find out who did it and maybe talk to them an see what their reputation is.
Buying a poorly rebuilt engine could be a nightmare.

You can use an F-Body LT1 PCM to run the LT4. You will need to ignore one of the two knock sensors on the Corvette engine. And of course you will need the LT4 program loaded into the LT1 PCM, or custom programming.
The front accessory mounts (alternator, PS, A/C, etc) and fuel connections to the rails are two differences that come to mind immediately.... nothing you couldn't swap over from the LT1 you already have. The LT4 will not have an EGR system.
Check the various part numbers against this:
LT1 vs. LT4
