Just glue the emblem in place with 3M Weatherstrip adhesive (comes in a tube, available at most Auto Body paint stores).
For the trim bead, just Google "vinyl piping" or search for it on ebay. Some fabric or marine upholstery stores that carry products for outdoor furniture may have it too.
Buy about 3 feet of the 5mm or 3/16" thick product. You should be able to find it in silver or clear vinyl over silver. I used white on mine (see photos below).
To install the piping cord, just press it into the the slot, starting in the center at the bottom and slowly working all the way around. Trim length to fit.
Both the rubber bumper and piping will each compress a bit to hold the cord in tightly without the need for an adhesive.
