Driver side vent - if memory serves, there's a rear retaining clip (I think). You have to pull the vent out slightly to get to it. As for getting behind the cluster, I had taken the seat out and was on my back when I did mine. It was, however, difficult to get in there. Once you replace it, I don't suggest you put the nut back on!
When you take the cluster out, be careful of the oil pressure line and the speedo cable. There's not much give in either.
Have you given any thought to different colors for the bulbs? I had my speedo rebuilt, and bought some blue sleeves for the bulbs. Instead of a glaring white night night, there's a soft blue one now. I did the same for the gear selector lighting. It looks pretty good and everything is still readable.
