Need help decideing what to do with my trim

The rocker trim (which was typically blacked out below) defines it as a 70 and IMHO should stay. A bumble bee stripe was also available in 70 and looks good. If you have a strip along the center body line midway up the door it wasn't factory, and I think it spoils the looks of the car and would interfere with the stripe. Most of these were "rub strips" designed to keep the doors from getting dinged in parking lots. I think they are uglier than door dings.

It's your car, do what you like, but that's my $.02.
