Welcome to the forum, Fed, glad you found us.
Stage 3 would mean that the cancer had escaped the prostate capsule. Possilbe they saw something on the MRI that indicated that. But the MRI is not 100% definitive. although its usually pretty good. Might have been a close call and they called it that way.
It is fairly common for a gleason score to be upgraded after surgery. Happens about 30-40% of the time. Less often, but sometimes, the gleason score is downgraded. So you were one of the "lucky"ones. (3+4) is low intermediate risk. Did you have negative margins? From what you say in your post, it looks like there is a good chance you've been cured.
