1. Technically there should be no difference, since you're got same checksums.
2. All it does - writes decryption key in reserved area in ISO. You simply can overwrite it.
3. Technically, when ps3 is running gameOS it should decrypt disc contents, so...And it's simpler to use PS3 because in that case you get gamedata already decrypted.
4. All i did was basic tool, which writes decryption key in specific ISO area. Unfortunately, i have no idea about complete IRD topology structure.
You can use reverse way to check, what's wrong - build encrypted ISO from decrypted files + IRD, and compare them with your untouched ISO. If encrypted files is different - then it's definitely something wrong with decryption keys in IRD.
