I didn't go for the entire package either. I did splurge for the Aviator seats and they are worth every penny, a little heavy, but your rear will thank you! A couple years ago I did OSH to Seattle in one day, almost 12 hours in the airplane that day, and the seats were great! I ordered the carpet kit with the baggage panels, but honestly, I never installed the side walls for the baggage area. I ordered the elbow rests instead of the molded side panels and although it's not quite as finished looking, I wanted the extra inch of space and reduce the weight. One thing I'm glad I did was have CA make a couple of custom pockets for each side. One pocket is mounted on the front of the spar and another is on the side wall next to the thigh.
This shows the armrest, but not the pockets (this pic was 400 hours ago with a lot less wear!)...
