What people who go blind need isn't clever life hacks. Those are nice, of course, but bump dots and stuff like that just make our lives more convenient.
What we need is emotional support. We just lost our eyesight, our careers, our driver's licenses, many of our hopes and dreams, and the respect we once earned has been replaced with pity. Bump dots aren't going to substitute.
Your friend needs you to be the same friend you've always been. Please don't treat him any different. Be the constant in his rapidly changing life. Everything he knows has just been replaced with a new reality he doesn't know - don't be someone he doesn't know, too. Make the changes blindness necessitates, but keep everything else you can the same.

Your friend is lucky to have you. Mistakes will be made - that's inevitable. You're both new at this. Things will get awkward and a little bit uncomfortable, but together you can work through that.
Finally, there isn't a right way to be blind. There's no right place to put bump dots on a keyboard, no correct way to arrange your living space, nothing like that. We're few and far between, connected by a shared blindness but separate from each other.
