As far as the spoke protector is concerned, it looks as if large plastic ones were original equipment along with big ugly reflectors in 1978. Here's the catalog page for the P-13. I also checked the other models and they appear to be wearing them as well.
Is this a picture of your Paramount above? If so it appears to be a very traditional Campus Green. Even if Campus Green was not on the list of available colors in 1978, I can't imagine Schwinn not having it in stock. There had to be 100s of 1000s of EF Schwinns painted this color from the late '60s through the mid '70s.
Does the component information for a road racing Paramount P13 also apply to a tour model as well? Yes! this is my '78 Paramount and I'm excited to get started putting it back to as near to original condition as possible. Being a complete newby to restoring vintage bicycles I am going to need some constructive guidance from you guys that will be very much appreciated.
