Calvinism is usually explained or defined using the TULIP acronym. I haven't explained it in a while, so I might be wrong in a place or two, miss out an important point or three, or stress something that isn't really important, but here goes. (ArcticFox or someone else can correct me as necessary.)
Total Depravity -- As a result of the Fall, people are slaves of sin with no desire to love or serve God. As a result, no man will even
want salvation if God does not give him that desire.
Unconditional Election -- God chooses those who are saved in a manner that does not depend on anything they have done.
Limited Atonement -- Jesus did not die for everyone; he only died for those who will be saved.
Irresistible Grace -- God's grace cannot be refused. Every person to whom God extends his saving grace is saved.
Perseverance of the Saints -- Once saved, a person cannot be lost. One cannot lose her salvation.

Yes. EucharisticAdoration mentioned John 9: 41
in this post but I don't think you addressed it. Can I can guess how you interpret it? That Jesus is saying if he hadn't come to this earth to do what he did, then we would've been with excuse, but since he came we are without excuse regardless of if we've heard of him or not.
