As far as lights ~the way it was intended was to use a handheld/headlamp to spot with and the gun mounted light to shoot with. There are a bunch of each on the market. Heck, you can experiment and make your own stuff. I will say this much though, if your in it for the long haul, but the best you can afford and be done with it. Light force has handheld and gun mounted lights. Optronics is another.
Can't answer the blind question.
Other items~ A turkey feather hanging on a string. One of those sqeeky dog toy thingys. A custom hand call. A cheep hand call. A foxpro. Just when you think you got what you need, there's always something new and improved.
There's a wealth of info on this and other sites. Might want to try this one........
