Nice post there death. Yeah that fuse panel door seems like a perfect place to mount the switches. They are out of the way, you can't bump them with your leg (unless maybe your trying to drive with your feet or something) and your not 'drilling' them into your dash (BIG MISTAKE and costly if you ever wanted to remove the switches as well as if you screw up). You can get a fuse panel door at a local insurance junkyard for pennies.... if not free.
Jess, another good thing too is that if you do opt to wire the power from the fuse panel to the switch, it's right there behind that fuse panel door so very very convenient and no worry to hide any wires for that since you will probably use a wire only a few inches long.
Vent LEDs, I never really got a 'vibe' for those. I would pass on those but that is just me. They do look cool if done correctly.
