Medlaw, we have all been where you are. Hearing that you or your spouse has cancer knocks the blocks from under you.....BUT---your husbands scores look very treatable and it sounds like his doctor is using sound preparation to get him ready for the surgery.
You've got to be strong for him and be encouraging. If you are church-goers, talk with your pastor. Mine pointed me toward a couple other guys that had PCa. Their insights and prayers were of great comfort. Encourage him to talk this out with others that have been through it.
If you are looking for a guide that helps in your building knowledge, one of my friends loaned me Dr. Patrick Wash's book on Surviving Prostate Cancer. It speaks plainly and from the doctor's experiences. It would be a good source for you.
My prayers are with you and him
