'54joe,
If your interior color is Pearl Beige (standard color) or Pulsar Gray (Deluxe color) all interior sheet metal is painted that color. However, I am not certain about the color of the seat frame - on my Suburban it was the interior color (Pulsar Gray) but I have seen sales pictures that do not have the Pickup's seat fram the same as the interior color.
The center of the verticle bars to the right and left of the radio-speaker grill are painted black (to look like the dark speaker openings in the grill).
Here is a DuPont sheet that specifies the trim colors and a sheet from the 1954 Engineering Specifications Manual:

Jim Carter sells a sheet that describes pinstriping location and stripe width. The original body stripe on my '54 Subruban was 1/8" wide but people have described stripes of 1/8" to 3/16". There were three stripes on wheels and they were supposedly about 3/16" wide (Jim Carter describes the location).
If you are interested, I could post a photo of my radio grill, body pin-stripe (we used striping tape and painted with a pinstriping brush), and a photo of a striped wheel (done by hand but it is not satisfactory). The way these wheels were/are painted is to touch the paint brush to a spinning wheel. I have never done this but have found a local bodyman who has done this (and will do it for me this winter).
