Thanks for posting this. It sounds like you made the right choice. I'm really happy for you.
Although I haven't had this done, I did have an open (shouldice) hernia repair done about 7 years ago, and it would probably be in a similar spot to your incision. It was a big-ass 3" or so incision in my left groin with stainless steel thread internally and staples, which were removed about a week later. It sucked, but if there's one thing that helped, it was being in a recliner or sleeping at about a 45* angle. The incision felt weird for a long time after that. To be honest, I think it was about a year before it didn't feel all tingly and gross to the touch.
I'm 72 hours post op now and can walk around the house, but that's about it. This is the last time I go into the scrotum and if this doesn't get me a big reduction in pain, I will most certainly be following in your footsteps.
Obviously it's too early to tell, but please let us know if there are any sexual side effects.
Man, maybe you could sue the doc who did your vasectomy, I mean, with the AUA guidelines not being told to you and ultimately losing your balls, I think you'd have quite the case!
