Striping tape is an easy find. Just about any auto parts store carries pinstriping tape in different widths.
Gold lettering? My sister has a business that does lettering that is Laser cut. The last time that I knew of, she had adhesive-backed real gold leaf that would be perfect for you. PM me and I'll give you her phone number. She does full-sized boat lettering and numbering plus she's done a lot of work for my boats. You might check around for a place near you also. Custom lettering/sign shops are found in most cities that can do the job for you.
