Yep, I highly recommend installing those two. I had my LED light installed in the left map light in the overhead console which is in my direct line of vision so I always see it whenever it goes off even when the music is going. It's simply not enough IMHO to be able to hear the warning. And on the other hand, it can get a bit annoying when its going off all the time in high "radar" area so its handy to have the mute button within reach. My control unit is in the same place as yours but my mute button is to the right of the steering wheel column just below the line that separates the top and bottom halves. I'll try to take a picture if you'd like. Works great this way. My kill switch is under the console too. This switch shuts off the entire system quickly and easy even though its possible to turn it off by using the volume switch on the control unit. My installer came up with a very efficient layout.
