Welcome Tuck, Im sure you will find a wealth of information here at the Club!
It pains me greatly to know you aren't considering a Tangerine XV (only kidding, all of the colors we have to pick from look great!
The grey and khaki are also two of my favorite colors. I know the pain of changing your mind every day!
In terms of the mods you have listed, if you are handy at all I think you will find the DIY instructions posted by members here very helpful, and save you a decent amount of $$$ from dealer installations.
